Once the ALKAL binds with ALK and dimerizes with another ALK-ALKAL complex, this activated conformation also initiates a conformational change of the intracellular kinase domain of ALK. This causes an autophosphorylation of several tyrosine residues of this domain, activating a signaling cascade with its kinase activity. | Once the ALKAL binds with ALK and dimerizes with another ALK-ALKAL complex, this activated conformation also initiates a conformational change of the intracellular kinase domain of ALK.

There are many <scene name='90/ | There are many <scene name='90/904317/Premutationresidues/1'>residues that could be mutated</scene> that would cause constitutive receptor activation, enhancement between the interaction of receptors or stabilization of active receptors are known to relate to oncogenic potentials (Figure 4). The <scene name='90/904317/His694/1'>His694</scene> that is mutated to an arginine is known to be a gain-of-function in lung adenocarcinoma which can lead to constitutive activation of ALK. The <scene name='90/904317/Phe856/1'>Phe856</scene> that is mutated to the a serine may cause a gain-of-function mutation that is linked to acute myeloid leukemia. When the <scene name='90/904318/Arg753/2'>Arg753</scene> is mutated to a glutamate it is commonly identified in histiocytic neoplasms. The <scene name='90/904318/Gly747/1'>Gly747</scene> changing to arginine could cause possible oncogenic potentials which are not specified yet. The F856S and R753Q mutations are known to increase cytokine-dependent cell proliferation in certain cells. <ref>DOI:10.1038/s41586-021-03959-5</ref> | ||
