Is predicted to encode a protein with the following domains: DENN domain, C-terminal lobe; dDENN domain; cDENN domain; uDENN domain; MAP kinase-activating death domain protein; and DENN (AEX-3) domain. Is an ortholog of C. elegans aex-3. In C. elegans, aex-3 is involved in several processes, including egg-laying behavior; mating; and positive regulation of digestive system process.
