Cellular component

SNX-BAR dimer, heterodimeric membrane-deforming retromer subcomplex, retromer complex, outer shell

The dimeric subcomplex of the retromer, believed to be peripherally associated with the membrane. This dimeric complex is responsible for remodeling endosomal membranes to form a tube-structure to which cargo molecules are selected for recycling. The budding yeast complex comprises Vps5p and Vps17p, and may contain multiple copies of a Vps5p/Vps17p dimer. The mammalian complex contains SNX1 or SNX2 dimerized with SNX5 or SNX6.
