Predicted to enable proton-transporting ATPase activity, rotational mechanism. Involved in intracellular pH reduction; positive regulation of programmed cell death; and spermatocyte division. Located in cytoplasm. Expressed in sperm and spermatocyte. Human ortholog(s) of this gene implicated in autosomal dominant congenital deafness with onychodystrophy and renal tubular acidosis. Is an ortholog of human ATP6V1B1 (ATPase H+ transporting V1 subunit B1) and ATP6V1B2 (ATPase H+ transporting V1 subunit B2).
Predicted to be involved in centrosome localization; intraciliary transport; and protein localization to cilium. Located in dendrite; neuronal cell body; and non-motile cilium. Expressed in ciliated neurons; sensory neurons; and tail. Is an ortholog of human IFT20 (intraflagellar transport 20).
