Is predicted to encode a protein with the following domains: Resistance to inhibitors of cholinesterase protein 3, N-terminal; Resistance to inhibitors of cholinesterase homologue 3; and Resistance to inhibitors of cholinesterase protein 3. Is an ortholog of C. elegans ric-3. In C. elegans, ric-3 is involved in several processes, including cholinergic synaptic transmission; positive regulation of cholinergic synaptic transmission; and protein localization to cell surface.
