Sorting nexin-5 (SNX5)

Involved in several stages of intracellular trafficking. Acts in part as part of the retromer membrane-deforming SNX-BAR subcomplex.

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 cargo protein recycling. The SNX-BAR subcomplex functions to deform the donor membrane to a tubular profile called endosome-to-TGN transport carrier (ETC) (Probable).
