SNX2 Proteins and Enzymes

SNX2 (Sorting nexin 2) is 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. SNX2 is a component of the retromer complex, a complex required to retrieve lysosomal enzyme receptors (IGF2R and M6PR) from endosomes to the trans-Golgi network. It may form oligomeric complexes with family members.
