Enables several functions, including ATPase binding activity; identical protein binding activity; and peptide hormone binding activity. Involved in several processes, including G protein-coupled receptor signaling pathway; activation of adenylate cyclase activity; and arachidonic acid secretion. Located in several cellular components, including endoplasmic reticulum; endosome; and lysosome. Is integral component of plasma membrane and intrinsic component of external side of plasma membrane. Part of receptor complex. Human ortholog(s) of this gene implicated in Leydig cell hypoplasia; Leydig cell tumor; breast cancer; familial male-limited precocious puberty; and gonadal disease. Orthologous to human LHCGR (luteinizing hormone/choriogonadotropin receptor). [provided by Alliance of Genome Resources, Apr 2022]
