Enables G protein-coupled receptor activity. Involved in adenylate cyclase-activating G protein-coupled receptor signaling pathway and negative regulation of smoothened signaling pathway involved in dorsal/ventral neural tube patterning. Located in cilium and recycling endosome. Is expressed in several structures, including central nervous system; eye; and limb. Orthologous to human GPR161 (G protein-coupled receptor 161).
