Involved in megakaryocyte development; platelet alpha granule organization; and regulation of platelet aggregation. Acts upstream of or within several processes, including collagen fibril organization; collagen metabolic process; and peptidyl-lysine hydroxylation. Predicted to be located in Golgi ap
paratus; cytoplasmic vesicle; and perinuclear region of cytoplasm. Predicted to be part of CORVET complex and HOPS complex. Predicted to be active in lysosome and synaptic vesicle. Is expressed in dorsal root ganglion; facial ganglion; glossopharyngeal ganglion; trigeminal ganglion; and vestibulo-cochlear ganglion. Used to study ARC syndrome. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita; arthrogryposis, renal dysfunction, and cholestasis 1; cholestasis; kidney disease; and progressive familial intrahepatic cholestasis. Orthologous to human VPS33B (VPS33B late endosome and lysosome associated). [provided by Alliance of Genome Resources, Jul 2025]
Acts upstream of or within several processes, including collagen fibril organization; collagen metabolic process; and protein modification process. Predicted to be located in Golgi apparatus and endosome. Predicted to be part of vesicle tethering complex. Predicted to be active in cytoplasm. Is expr
essed in several structures, including central nervous system; retina layer; and skeletal muscle. Used to study ARC syndrome. Human ortholog(s) of this gene implicated in arthrogryposis, renal dysfunction, and cholestasis 2. Orthologous to human VIPAS39 (VPS33B interacting protein, apical-basolateral polarity regulator, spe-39 homolog). [provided by Alliance of Genome Resources, Apr 2025]
