Summary: Enables corticotropin-releasing hormone receptor activity and peptide hormone binding activity. Involved in several processes, including negative regulation of secretion; regulation of gene expression; and regulation of intracellular signal transduction. Located in several cellular components, including axon; cell body fiber; and perikaryon. Used to study colitis; ischemia; and muscular atrophy. Biomarker of colitis; functional colonic disease; irritable bowel syndrome; and mental depression. Human ortholog(s) of this gene implicated in asthma. Orthologous to human CRHR2 (corticotropin releasing hormone receptor 2). [provided by Alliance of Genome Resources, Apr 2022]

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.
