Predicted to be involved in lysosomal protein catabolic process. Predicted to act upstream of or within several processes, including flagellated sperm motility; social behavior; and sperm mitochondrion organization. Predicted to be located in several cellular components, including bounding membrane of organelle; neuronal dense core vesicle lumen; and sperm midpiece. Predicted to be extrinsic component of membrane. Human ortholog(s) of this gene implicated in choreaacanthocytosis and choreatic disease. Orthologous to human VPS13A (vacuolar protein sorting 13 homolog A). [provided by Alliance of Genome Resources, Apr 2022]
