&lt;br /&gt;
&#039;&#039;&#039;BACKGROUND&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein (pRb)is a regulatory protein that regulates cell growth. It does this by preventing the cell from replicating damaged DNA. It thus keeps the cell in the G1 phase and does not allow the cell to enter the S phase with damaged DNA. This protein is one that is commonly mutated in many types of cancer. The retinoblastoma gene that codes for the protein is a tumor suppressor gene, or a gene that protects a cell from one step on the path to cancer. One can tell early in one&#039;s life if they possess mutations in this gene because often mutations in this gene cause the person to develop retinoblastoma cancer, hence the name retinoblastoma. While retinoblastoma cancer is located in the eye, the protein is found in all cells in the human body. It is currently unknown why early mutations in this gene cause retinoblastoma cancer. &lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein has two main domains (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/2&#039;&amp;gt;Domain A&amp;lt;/scene&amp;gt; and &lt;br /&gt;
&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_b/1&#039;&amp;gt;Domain B&amp;lt;/scene&amp;gt;). At the interface of these two domains, there is a pocket that is able to bind and inhibit E2F (transcription factor). You can see pRb bound to E2F &amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/E2f/1&#039;&amp;gt;here&amp;lt;/scene&amp;gt;. The structure on the bottom right shows pRb bound to E2F. Here, pRb is the green and blue structures. It is the same structure as above, but with added E2F sequences. The role of E2F is to promote the cell into the S phase. Since pRb binds E2F, then it inhibits the cell from entering the S phase.  pRb is active when it is not phosphorylated, however when cyclin-dependent kinases (CDK) and cyclins phosphorylate pRb it inactivates the protein. Once it becomes phosphorylated, it releases E2F and then the cell can enter the S phase.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;EXPERIMENTAL OBSERVATIONS IN TUMORS&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Several genetics studies have been done on the RB gene and on its affect on many different types of cancer. In retinoblastoma tumors, there is no evidence of any pRb in these tumor cells. Because of the absence of pRb, these cells have a very high change of becoming cancerous. It has been concluded that RB gene inactivation is universal in all retinoblastomas and that pRb is rapidly degraded in these tumors. The inactivation of the RB gene is universal in retinoblastomas, but it plays a factor in many other cancers as well. It has been shown that mutations in the Rb gene could lead to reduced levels of pRb in other cancers including: Small Cell Lung Carcinomas (SCLC), bladder, breast, and a few others.  &lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;BACKGROUND&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein (pRb)is a regulatory protein that regulates cell growth. It does this by preventing the cell from replicating damaged DNA. It thus keeps the cell in the G1 phase and does not allow the cell to enter the S phase with damaged DNA. This protein is one that is commonly mutated in many types of cancer. The retinoblastoma gene that codes for the protein is a tumor suppressor gene, or a gene that protects a cell from one step on the path to cancer. One can tell early in one&#039;s life if they possess mutations in this gene because often mutations in this gene cause the person to develop retinoblastoma cancer, hence the name retinoblastoma. While retinoblastoma cancer is located in the eye, the protein is found in all cells in the human body. It is currently unknown why early mutations in this gene cause retinoblastoma cancer. &lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein has two main domains (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/2&#039;&amp;gt;Domain A&amp;lt;/scene&amp;gt; and &lt;br /&gt;
&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_b/1&#039;&amp;gt;Domain B&amp;lt;/scene&amp;gt;). At the interface of these two domains, there is a pocket that is able to bind and inhibit E2F (transcription factor). You can see pRb bound to E2F &amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/E2f/1&#039;&amp;gt;here&amp;lt;/scene&amp;gt;. The role of E2F is to promote the cell into the S phase. Since pRb binds E2F, then it inhibits the cell from entering the S phase.  pRb is active when it is not phosphorylated, however when cyclin-dependent kinases (CDK) and cyclins phosphorylate pRb it inactivates the protein. Once it becomes phosphorylated, it releases E2F and then the cell can enter the S phase.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;EXPERIMENTAL OBSERVATIONS IN TUMORS&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Several genetics studies have been done on the RB gene and on its affect on many different types of cancer. In retinoblastoma tumors, there is no evidence of any pRb in these tumor cells. Because of the absence of pRb, these cells have a very high change of becoming cancerous. It has been concluded that RB gene inactivation is universal in all retinoblastomas and that pRb is rapidly degraded in these tumors. The inactivation of the RB gene is universal in retinoblastomas, but it plays a factor in many other cancers as well. It has been shown that mutations in the Rb gene could lead to reduced levels of pRb in other cancers including: Small Cell Lung Carcinomas (SCLC), bladder, breast, and a few others.  &lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;BACKGROUND&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein (pRb)is a regulatory protein that prevents the cell from replicating damaged DNA. It thus keeps the cell in the G1 phase and does not allow the cell to enter the S phase with damaged DNA. This protein is one that is commonly mutated in many types of cancer. The retinoblastoma gene that codes for the protein is a tumor suppressor gene, or a gene that protects a cell from one step on the path to cancer. One can tell early in one&#039;s life if they possess mutations in this gene because often mutations in this gene cause the person to develop retinoblastoma cancer, hence the name retinoblastoma. While retinoblastoma cancer is located in the eye, the protein is found in all cells in the human body. It is currently unknown why early mutations in this gene cause retinoblastoma cancer. &lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein has two main domains (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/2&#039;&amp;gt;Domain A&amp;lt;/scene&amp;gt; and &lt;br /&gt;
&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_b/1&#039;&amp;gt;Domain B&amp;lt;/scene&amp;gt;). At the interface of these two domains, there is a pocket that is able to bind and inhibit E2F (transcription factor). You can see pRb bound to E2F &amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/E2f/1&#039;&amp;gt;here&amp;lt;/scene&amp;gt;. The role of E2F is to promote the cell into the S phase. Since pRb binds E2F, then it inhibits the cell from entering the S phase.  pRb is active when it is not phosphorylated, however when cyclin-dependent kinases (CDK) and cyclins phosphorylate pRb it inactivates the protein. Once it becomes phosphorylated, it releases E2F and then the cell can enter the S phase.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;EXPERIMENTAL OBSERVATIONS IN TUMORS&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Several genetics studies have been done on the RB gene and on its affect on many different types of cancer. In retinoblastoma tumors, there is no evidence of any pRb in these tumor cells. It has been concluded that RB gene inactivation is universal in all retinoblastomas and that pRb is rapidly degraded in these tumors. The inactivation of the RB gene is universal in retinoblastomas, but it plays a factor in many other cancers as well.  &lt;br /&gt;

Retinoblastoma protein has two main domains (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/2&#039;&amp;gt;Domain A&amp;lt;/scene&amp;gt; and &lt;br /&gt;
&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_b/1&#039;&amp;gt;Domain B&amp;lt;/scene&amp;gt;). At the interface of these two domains, there is a pocket that is able to bind and inhibit E2F (transcription factor). You can see pRb bound to E2F &amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/E2f_and_prb/1&#039;&amp;gt;here&amp;lt;/scene&amp;gt;. The role of E2F is to promote the cell into the S phase. Since pRb binds E2F, then it inhibits the cell from entering the S phase.  pRb is active when it is not phosphorylated, however when cyclin-dependent kinases (CDK) and cyclins phosphorylate pRb it inactivates the protein. Once it becomes phosphorylated, it releases E2F and then the cell can enter the S phase.&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;EXPERIMENTAL OBSERVATIONS IN TUMORS&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Several genetics studies have been done on the RB gene and on its affect on many different types of cancer. In retinoblastoma tumors, there is no evidence of any pRb in these tumor cells. It has been concluded that RB gene inactivation is universal in all retinoblastomas and that pRb is rapidly degraded in these tumors. The inactivation of the RB gene is universal in retinoblastomas, but it plays a factor in many other cancers as well.  &lt;br /&gt;

&#039;&#039;&#039;BACKGROUND&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein (pRb)is a regulatory protein that prevents the cell from replicating damaged DNA. It thus keeps the cell in the G1 phase and does not allow the cell to enter the S phase with damaged DNA. This protein is one that is commonly mutated in many types of cancer. The retinoblastoma gene that codes for the protein is a tumor suppressor gene, or a gene that protects a cell from one step on the path to cancer. One can tell early in one&#039;s life if they possess mutations in this gene because often mutations in this gene cause the person to develop retinoblastoma cancer, hence the name retinoblastoma. While retinoblastoma cancer is located in the eye, the protein is found in all cells in the human body.

&lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein (pRb)is a regulatory protein that prevents the cell from replicating damaged DNA. It thus keeps the cell in the G1 phase and does not allow the cell to enter the S phase with damaged DNA. This protein is one that is commonly mutated in cancer. The retinoblastoma gene that codes for the protein is a tumor suppressor gene, or a gene that protects a cell from one step on the path to cancer. One can tell early in one&#039;s life if they possess mutations in this gene because often mutations in this gene cause the person to develop retinoblastoma cancer, hence the name retinoblastoma. While retinoblastoma cancer is located in the eye, the protein is found in all cells in the human body. It is currently unknown why early mutations in this gene cause retinoblastoma cancer. &lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein has two main domains (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/2&#039;&amp;gt;Domain A&amp;lt;/scene&amp;gt; and &lt;br /&gt;
&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_b/1&#039;&amp;gt;Domain B&amp;lt;/scene&amp;gt;). At the interface of these two domains, there is a pocket that is able to bind and inhibit E2F (transcription factor). The role of E2F is to promote the cell into the S phase. Since pRb binds E2F, then it inhibits the cell from entering the S phase. pRb is active when it is not phosphorylated, however when cyclin-dependent kinases (CDK) and cyclins phosphorylate pRb it inactivates the protein. Once it becomes phosphorylated, it releases E2F and then the cell can enter the S phase.&lt;br /&gt;

&#039;&#039;&#039;BACKGROUND&#039;&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
Retinoblastoma protein is a regulatory protein that prevents the cell from replicating damaged DNA. It thus keeps the cell in the G1 phase and does not allow the cell to enter the S phase with damaged DNA. This protein is one that is commonly mutated in cancer. The retinoblastoma gene that codes for the protein is a tumor suppressor gene, or a gene that protects a cell from one step on the path to cancer. One can tell early in one&#039;s life if they possess mutations in this gene because often mutations in this gene cause the person to develop retinoblastoma cancer, hence the name retinoblastoma. While retinoblastoma cancer is located in the eye, the protein is found in all cells in the human body. It is currently unknown why early mutations in this gene cause retinoblastoma cancer. The protein has two main domains (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/2&#039;&amp;gt;Domain A&amp;lt;/scene&amp;gt;)&lt;br /&gt;

Structure of the retinoblastoma protein pocket domain in complex with adenovirus E1A CR1 domain&lt;br /&gt;
Publication Abstract from PubMed&lt;br /&gt;
&lt;br /&gt;
The adenovirus (Ad) E1A (Ad-E1A) oncoprotein mediates cell transformation, in part, by displacing E2F transcription factors from the retinoblastoma protein (pRb) tumor suppressor. In this study we determined the crystal structure of the pRb pocket domain in complex with conserved region 1 (CR1) of Ad5-E1A. The structure and accompanying biochemical studies reveal that E1A-CR1 binds at the interface of the A (&amp;lt;scene name=&#039;Chad_Sorenson_sandbox_1/Domain_a/1&#039;&amp;gt;(Domain A)&amp;lt;/scene&amp;gt;)and B cyclin folds of the pRb pocket domain, and that both E1A-CR1 and the E2F transactivation domain use similar conserved nonpolar residues to engage overlapping sites on pRb, implicating a novel molecular mechanism for pRb inactivation by a viral oncoprotein.&lt;br /&gt;

===Human p53 core domain with hot spot mutation R249S (I)===&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Publication Abstract from PubMed&lt;br /&gt;
--------------------------------------------------------------------------------&lt;br /&gt;
 &lt;br /&gt;
The tumor suppressor protein p53 is mutated in more than 50% of invasive cancers. About 30% of the mutations are found in six major &amp;quot;hot spot&amp;quot; codons located in its DNA binding core domain. To gain structural insight into the deleterious effects of such mutations and their rescue by suppressor mutations, we determined the crystal structures of the p53 core domain incorporating the hot spot mutation &amp;lt;scene name=&#039;Ann_Taylor_sandbox_8/R249s/1&#039;&amp;gt;R249S&amp;lt;/scene&amp;gt;, the core domain incorporating R249S and a second-site suppressor mutation H168R (referred to as the double mutant R249S/H168R) and its sequence-specific complex with DNA and of the triple mutant R249S/H168R/T123A. The structural studies were accompanied by transactivation and apoptosis experiments. The crystal structures show that the region at the vicinity of the mutation site in the R249S mutant displays a range of conformations [wild-type (wt) and several mutant-type conformations] due to the loss of stabilizing interactions mediated by R249 in the wt protein. As a consequence, the protein surface that is critical to the formation of functional p53-DNA complexes, through protein-protein and protein-DNA interactions, is largely distorted in the mutant conformations, thus explaining the protein&#039;s &amp;quot;loss of function&amp;quot; as a transcription factor. The structure of this region is restored in both R249S/H168R and R249S/H168R/T123A and is further stabilized in the complex of R249S/H168R with DNA. Our functional data show that the introduction of H168R as a second-site suppressor mutation partially restores the transactivation capacity of the protein and that this effect is further amplified by the addition of a third-site mutation T123A. These findings together with previously reported data on wt and mutant p53 provide a structural framework for understanding p53 dysfunction as a result of oncogenic mutations and its rescue by suppressor mutations and for a potential drug design aimed at restoring wt activity to aberrant p53 proteins. &lt;br /&gt;
