Mchr1 Gene Summary [Rat]
Enables hormone binding activity and melanin-concentrating hormone receptor activity. Involved in cell surface receptor signaling pathway; positive regulation of calcium ion transport; and positive regulation of cytosolic calcium ion concentration. Predicted to be located in ciliary membrane and non-motile cilium. Predicted to be active in neuron projection and plasma membrane. Biomarker of obesity. Human ortholog(s) of this gene implicated in morbid obesity. Orthologous to human MCHR1 (melanin concentrating hormone receptor 1). [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 Mchr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
