A PHARMACOLOGICAL MAP OF THE PI3-K FAMILY DEFINES A ROLE FOR P110ALPHA IN SIGNALING: THE STRUCTURE OF COMPLEX OF PHOSPHOINOSITIDE 3-KINASE GAMMA WITH INHIBITOR PIK-93

Overview

Phosphoinositide 3-kinases (PI3-Ks) are an important emerging class of, drug targets, but the unique roles of PI3-K isoforms remain poorly, defined. We describe here an approach to pharmacologically interrogate the, PI3-K family. A chemically diverse panel of PI3-K inhibitors was, synthesized, and their target selectivity was biochemically enumerated, revealing cryptic homologies across targets and chemotypes. Crystal, structures of three inhibitors bound to p110gamma identify a, conformationally mobile region that is uniquely exploited by selective, compounds. This chemical array was then used to define the PI3-K isoforms, required for insulin signaling. We find that p110alpha is the primary, insulin-responsive PI3-K in cultured cells, whereas p110beta is, dispensable but sets a ... [(full description)]
