Plays a role in vesicular protein sorting. Required for the endosome-to-Golgi retrieval of the vacuolar protein sorting receptor pep1/vps10. Component of the membrane-associated retromer complex which is essential in endosome-to-Golgi retrograde transport. The vps29-vps26-vps35 subcomplex may be involved in cargo selection. Component of the retromer complex which consists of vps29, vps6, vps35, vps5 and vps17. Belongs to the VPS17 family.
