Predicted to enable proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in proton transmembrane transport. Predicted to be part of vacuolar proton-transporting V-type ATPase, V0 domain. Is an ortholog of C. elegans
vha-5. In C. elegans,
vha-5 is involved in several processes, including collagen and cuticulin-based cuticle development; exosomal secretion; and multicellular organismal-level water homeostasis.
