Lnpep Gene Summary [Mouse]
Enables aminopeptidase activity. Involved in negative regulation of cold-induced thermogenesis. Acts upstream of or within protein catabolic process. Located in cytoplasmic vesicle membrane; perinuclear region of cytoplasm; and plasma membrane. Is expressed in extraembryonic component; labyrinthine zone; and placenta. Human ortholog(s) of this gene implicated in type 2 diabetes mellitus. Orthologous to human LNPEP (leucyl and cystinyl aminopeptidase). [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 mouse Lnpep often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
