Summary: Enables cholecystokinin receptor activity. Involved in several processes, including positive regulation of somatostatin secretion; reduction of food intake in response to dietary excess; and regulation of metal ion transport. Located in endosome and terminal bouton. Used to study obesity and type 2 diabetes mellitus. Biomarker of pancreatic cancer. Human ortholog(s) of this gene implicated in obesity. Orthologous to human CCKAR (cholecystokinin A receptor). [provided by Alliance of Genome Resources, Dec 2024]
Expression: Biased expression in Spleen (RPKM 12.6), Liver (RPKM 3.7) and 4 other tissues See more

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.
