STRUCTURE OF THE PX DOMAIN FROM P40PHOX BOUND TO PHOSPHATIDYLINOSITOL 3-PHOSPHATE
Overview
More than 50 human proteins with a wide range of functions have a 120, residue phosphoinositide binding module known as the PX domain. The 1.7 A, X-ray crystal structure of the PX domain from the p40(phox) subunit of, NADPH oxidase bound to PtdIns(3)P shows that the PX domain embraces the, 3-phosphate on one side of a water-filled, positively charged pocket and, reveals how 3-phosphoinositide specificity is achieved. A chronic, granulomatous disease (CGD)-associated mutation in the p47(phox) PX domain, that abrogates PtdIns(3)P binding maps to a conserved Arg that does not, directly interact with the phosphoinositide but instead appears to, stabilize a critical lipid binding loop. The SH3 domain present in the, full-length protein does not affect soluble PtdIns(3)P binding to the, p40(phox) PX domain.
