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]
