Predicted to enable ATP binding activity and proton-transporting ATPase activity, rotational mechanism. Predicted to be involved in ATP metabolic process and proton transmembrane transport. Predicted to be part of proton-transporting V-type ATPase, V1 domain. Is an ortholog of C. elegans
spe-5. In C. elegans,
spe-5 is involved in intracellular pH reduction; positive regulation of programmed cell death; and spermatocyte division.
