Kazi, and Lars R nstrand1 From Experimental Clinical Chemistry, Wallenberg Laboratory, Department of Laboratory Medicine, Lund University, Sk e University Hospital, 20502 Malm SwedenBackground: Phosphorylation of Tyr-823 inside the A-loop of c-Kit will not be necessary for kinase activity but could have other functions. Outcomes: Mutation of Tyr-823 in c-Kit causes alterations in downstream signaling and a reduction in ligand-dependent cell survival and proliferation. Conclusion: Phosphorylation of Tyr-823 regulates c-Kit stability. Significance: This gives a function for the activation loop tyrosine of c-Kit. The receptor tyrosine kinase c-Kit, also called the stem cell element receptor, plays a important function in numerous developmental processes. Activating mutations in c-Kit cause alteration of those cellular processes and have already been implicated in numerous human cancers for instance gastrointestinal stromal tumors, acute myeloid leukemia, testicular seminomas and mastocytosis.Sibeprenlimab Regulation of the catalytic activity of numerous kinases is identified to become governed by phosphorylation of tyrosine residues in the activation loop in the kinase domain.Tanezumab Nevertheless, in the case of c-Kit phosphorylation of Tyr-823 has been demonstrated to become a late occasion which is not required for kinase activation.PMID:23912708 Nonetheless, for the reason that phosphorylation of Tyr-823 is really a ligand-activated occasion, we sought to investigate the functional consequences of Tyr-823 phosphorylation. By using a tyrosine-to-phenylalanine mutant of tyrosine 823, we investigated the effect of Tyr-823 on c-Kit signaling. We demonstrate here that Tyr-823 is critical for cell survival and proliferation and that mutation of Tyr-823 to phenylalanine results in decreased sustained phosphorylation and ubiquitination of c-Kit as compared with all the wild-type receptor. Moreover, the mutated receptor was, upon ligand-stimulation, immediately internalized and d.
