Predicted to enable oxidoreductase activity, acting on the CH-OH group of donors, NAD or NADP as acceptor. Predicted to be involved in steroid biosynthetic process. Is an ortholog of C. elegans F13D11.4; C32D5.12; and
bus-5. In C. elegans,
hsd-1 is involved in nematode larval development and sterol biosynthetic process.
