Structural basis for the auto-inhibition of c-Abl tyrosine kinase
Overview
c-Abl is normally regulated by an autoinhibitory mechanism, the disruption, of which leads to chronic myelogenous leukemia. The details of this, mechanism have been elusive because c-Abl lacks a phosphotyrosine residue, that triggers the assembly of the autoinhibited form of the closely, related Src kinases by internally engaging the SH2 domain. Crystal, structures of c-Abl show that the N-terminal myristoyl modification of, c-Abl 1b binds to the kinase domain and induces conformational changes, that allow the SH2 and SH3 domains to dock onto it. Autoinhibited c-Abl, forms an assembly that is strikingly similar to that of inactive Src, kinases but with specific differences that explain the differential, ability of the drug STI-571/Gleevec/imatinib (STI-571) to inhibit the, catalytic activity of Abl, but not that of c-Src.
Disease
Known diseases associated with this structure: Leukemia, Philadelphia chromosome-positive, resistant to imatinib OMIM:[189980]
