Crystal Structure of Human Pirin in complex with Triphenyl Compound
Structural highlights
Function[PIR_HUMAN] Possible transcriptional coregulator. May contribute to the regulation of cellular processes via its interaction with BCL3. May be required for efficient terminal myeloid maturation of hematopoietic cells. May play a role in the regulation of cell migration. May promote apoptosis when overexpressed. Has quercetin 2,3-dioxygenase activity (in vitro).[1] [2] [3] [4] Evolutionary Conservation Check, as determined by ConSurfDB.

Publication Abstract from PubMedThe discovery of small molecules that bind to a specific target and disrupt the function of proteins is an important step in chemical biology, especially for poorly characterized proteins. Human pirin is a nuclear protein of unknown function that is widely expressed in punctate subnuclear structures in human tissues. Here, we report the discovery of a small molecule that binds to pirin. We determined how the small molecule bound to pirin by solving the cocrystal structure. Either knockdown of pirin or treatment with the small molecule inhibited melanoma cell migration. Thus, inhibition of pirin by the small molecule has led to a greater understanding of the function of pirin and represents a new method of studying pirin-mediated signaling pathways. A small-molecule inhibitor shows that pirin regulates migration of melanoma cells.,Miyazaki I, Simizu S, Okumura H, Takagi S, Osada H Nat Chem Biol. 2010 Sep;6(9):667-73. Epub 2010 Aug 15.
