CRYSTAL STRUCTURE OF THE YEAST PX-DOMAIN PROTEIN GRD19P (SORTING NEXIN 3) COMPLEXED TO PHOSPHATIDYLINOSYTOL-3-PHOSPAHTE.

OverviewOverview

Phox homology (PX) domains have been recently identified in a number of, different proteins and are involved in various cellular functions such as, vacuolar targeting and membrane protein trafficking. It was shown that, these modules of about 130 amino acids specifically binding to, phosphoinositides and that this interaction is crucial for their cellular, function. The yeast genome contains 17 PX domain proteins. One of these, Grd19p, is involved in the localization of the late Golgi membrane, proteins DPAP A and Kex2p. Grd19p consists of the PX domain with 30 extra, residues at the N-terminal and is homologous to the functionally, characterized human sorting nexin protein SNX3. We determined the 2.0 A, crystal structure of Grd19p in the free form and in complex with, ... [(full description)]
