  • The inadvertent activation of the Abelson tyrosine kinase (Abl) causes chronic myelogenous leukemia (CML. [...] Key Result Critical to the binding of STI-571 is the adoption by the kinase of an inactive conformation, in which a centrally located "activation loop" is not phosphorylated. The conformation of this loop is distinct from that in active protein kinases, as well as in the inactive form of the closely related Src kinases. These results suggest that compounds that exploit the distinctive inactivation…Expand Abstract
