Enables corticotropin-releasing hormone binding activity. Involved in several processes, including cellular response to estrogen stimulus; cellular response to immobilization stress; and cellular response to organic cyclic compound. Located in several cellular components, including axon; cytoplasmic vesicle; and perikaryon. Biomarker of mental depression; obesity; and temporal lobe epilepsy. Human ortholog(s) of this gene implicated in mental depression. Orthologous to human CRHBP (corticotropin releasing hormone binding protein). [provided by Alliance of Genome Resources, Apr 2022]
