Molecular Basis for PI(3,5)P2 Recognition by SNX11, a Protein Involved in Lysosomal Degradation and Endosome Homeostasis Regulation.

Abstract excerpt

Phosphatidylinositol 3,5-bisphosphate (PI(3,5)P2) is an essential phosphoinositide required for endosome homeostasis and sorting for lysosomal degradation; however, the underlying mechanisms, especially in mammals, remain elusive or unexplored. Here we determined a structure of PI(3,5)P2 bound to Sorting Nexin 11 (SNX11) with an opened PPII-C loop. We also obtained an SNX11 structure with its PPII-C in "closed"...
