Target

Full Name
vacuolar protein sorting 33 homolog B (yeast)
Introduction
VPS33B is a member of the Sec-1 domain family, and encodes the human ortholog of rat Vps33b which is homologous to the yeast class C Vps33 protein. The mammalian class C vacuolar protein sorting proteins are predominantly associated with late endosomes/lysosomes, and like their yeast counterparts, may mediate vesicle trafficking steps in the endosome/lysosome pathway. Mutations in VPS33B are associated with arthrogryposis-renal dysfunction-cholestasis syndrome.

Alternative Names
VPS33B, Late Endosome And Lysosome Associated; Vacuolar Protein Sorting 33 Homolog B (Yeast); Vacuolar Protein Sorting 33B (Yeast Homolog); HVPS33B
Function
May play a role in vesicle-mediated protein trafficking to lysosomal compartments and in membrane docking/fusion reactions of late endosomes/lysosomes. Mediates phagolysosomal fusion in macrophages (PubMed:18474358).
Proposed to be involved in endosomal maturation implicating VIPAS39. In epithelial cells, the VPS33B:VIPAS39 complex may play a role in the apical recycling pathway and in the maintenance of the apical-basolateral polarity (PubMed:20190753).
Seems to be involved in the sorting of specific cargos from the trans-Golgi network to alpha-granule-destined multivesicular bodies (MVBs) promoting MVBs maturation in megakaryocytes (By similarity).

Recycling endosome
Colocalizes in clusters with VIPAS39 at cytoplasmic organelles (PubMed:19109425).
Colocalizes with RAB11A and VIPAS39 on recycling endosomes (PubMed:22753090).
Colocalizes with AP-3, clathrin, Rab5 and Rab7b (PubMed:21411634).
Colocalizes with M.tuberculosis PtpA in the cytosol of tuberculosis-infected macrophages and associates with phagosomes (PubMed:18474358).
Involvement in disease
Arthrogryposis, renal dysfunction and cholestasis syndrome 1 (ARCS1):
A multisystem disorder, characterized by neurogenic arthrogryposis multiplex congenita, renal tubular dysfunction and neonatal cholestasis with bile duct hypoplasia and low gamma glutamyl transpeptidase activity. Platelet dysfunction is common.
PTM
Phosphorylated on tyrosine residues.
(Microbial infection) Dephosphorylated by M.tuberculosis PtpA, which induces the reduction of host phagolysosome fusion in M.tuberculosis-infected macrophages.
