Is predicted to encode a protein with the following domains: PLAT/LH2 domain; RUN domain; RUN domain superfamily; Triose-phosphate Transporter family; Sugar phosphate transporter domain; cDENN domain; DENN (AEX-3) domain; dDENN domain; PLAT/LH2 domain superfamily; and uDENN domain. Is an ortholog of C. elegans
pkd-2. In C. elegans,
pkd-2 is involved in calcium ion transport; response to hermaphrodite contact; and vulval location.
