Lhcgr Gene Summary [Rat]
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 positive regulation of calcium ion transmembrane transport. Located in endosome and extracellular space. 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, Jul 2025]
