Phosphorylation of conserved phosphoinositide binding pocket regulates sorting nexin membrane targeting
Abstract
Sorting nexin 3 (SNX3) is a phosphatidylinositol 3-phosphate binding protein that localizes to early endosomes. Here the authors use NMR to resolve SNX3′s membrane interactions, revealing that membrane binding is regulated through phosphorylation of a conserved serine by its lipid recognition site.
