Predicted to be involved in several processes, including megakaryocyte development; melanosome localization; and vesicle organization. Predicted to act upstream of or within collagen fibril organization; collagen metabolic process; and peptidyl-lysine hydroxylation. Is active in synaptic vesicle. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita; arthrogryposis, renal dysfunction, and cholestasis 1; cholestasis; and kidney disease. Orthologous to human VPS33B (VPS33B late endosome and lysosome associated). [provided by Alliance of Genome Resources, Apr 2022]
