==Overview==

Src family kinases are maintained in an assembled, inactive conformation, by intramolecular interactions of their SH2 and SH3 domains. Full, catalytic activity requires release of these restraints as well as, phosphorylation of Tyr-416 in the activation loop. In previous structures, of inactive Src kinases, Tyr-416 and flanking residues are disordered. We, report here four additional c-Src structures in which this segment adopts, an ordered but inhibitory conformation. The ordered activation loop forms, an alpha helix that stabilizes the inactive conformation of the kinase, domain, blocks the ...
