Sorting nexin-2 (SNX2)

Involved in many stages of intracellular trafficking. Acts in part as part of the retromer membrane-deforming SNX-BAR subcomplex (PubMed:17101778).

The SNX-BAR retromer mediates retrograde transport of cargo proteins from endosomes into the trans-Golgi network (TGN) and is included in endosome-to-plasma membrane transport for freight protein recycling. The SNX-BAR subcomplex works to deform the donor membrane into a tubular profile called endosome-to-TGN transport carrier (ETC) (Probable).
