Predicted to be involved in endosome to lysosome transport and intracellular protein transport. Predicted to act upstream of or within cellular protein modification process; collagen fibril organization; and collagen metabolic process. Predicted to be located in Golgi apparatus and endosome. Predicted to be active in cytoplasm. 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 2022]
