Sorting nexin-3 is a protein that in humans is encoded by the SNX3 gene.This gene encodes a member of the sorting nexin family. Members of this family contain a phox (PX) domain which is a phosphoinositide binding domain and are involved in intracellular trafficking. This protein does not contain a coiled coil region like most family members. This protein interacts with phosphatidylinositol-3-phosphate and is involved in protein trafficking.
