Gcgr Gene Summary [Rat]
Enables glucagon receptor activity and peptide hormone binding activity. Involved in adenylate cyclase-activating G protein-coupled receptor signaling pathway; exocytosis; and hormone-mediated signaling pathway. Located in endosome. Human ortholog(s) of this gene implicated in Mahvash Disease and type 2 diabetes mellitus. Orthologous to human GCGR (glucagon receptor). [provided by Alliance of Genome Resources, Jul 2025]

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 rat Gcgr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
