Is predicted to encode a protein with the following domains: uDENN domain; PLAT/LH2 domain; DENN (AEX-3) domain; RUN domain; PLAT/LH2 domain superfamily; RUN domain superfamily; dDENN domain; and cDENN 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.
