Summary: Enables hormone binding activity and melanin-concentrating hormone receptor activity. Involved in cell surface receptor signaling pathway; positive regulation of calcium ion transport; and positive regulation of cytosolic calcium ion concentration. Predicted to be located in ciliary membrane and non-motile cilium. Predicted to be active in neuron projection and plasma membrane. Biomarker of obesity. Human ortholog(s) of this gene implicated in morbid obesity. Orthologous to human MCHR1 (melanin concentrating hormone receptor 1). [provided by Alliance of Genome Resources, Dec 2024]

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.
