Summary: Enables cytoskeletal motor activity. Involved in motor learning. Acts upstream of or within locomotory behavior; neuromuscular process controlling balance; and neuronal action potential. Predicted to be located in ciliary membrane; cytoplasm; and nucleus. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; ear; genitourinary system; nervous system; and skeleton. Orthologous to human GPR88 (G protein-coupled receptor 88).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
