Is predicted to encode a protein with the following domains: MAP kinase-activating death domain protein; dDENN domain; DENN (AEX-3) domain; cDENN domain; and uDENN 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.
