Enables growth hormone-releasing hormone activity. Involved in several processes, including circadian sleep/wake cycle, non-REM sleep; growth hormone secretion; and positive regulation of cell communication. Located in axon terminus; extracellular space; and perikaryon. Used to study myocardial infarction and prostatic hypertrophy. Biomarker of sleep disorder. Human ortholog(s) of this gene implicated in autoimmune polyendocrine syndrome type 1; endometrial cancer; ovarian cancer; and renal cell carcinoma. Orthologous to human GHRH (growth hormone releasing hormone). [provided by Alliance of Genome Resources, Apr 2022]
