Ghrhr Gene Summary [Mouse]
Enables growth hormone-releasing hormone receptor activity and peptide hormone binding activity. Involved in positive regulation of cell population proliferation. Acts upstream of or within several processes, including determination of adult lifespan; positive regulation of growth hormone secretion; and regulation of signal transduction. Located in plasma membrane. Is expressed in alimentary system; brain; metanephros; and spinal cord. Human ortholog(s) of this gene implicated in isolated growth hormone deficiency and isolated growth hormone deficiency type IB. Orthologous to human GHRHR (growth hormone releasing hormone receptor).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Ghrhr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
