Mttp Gene Summary [Mouse]

Enables cholesterol transfer activity; phosphatidylethanolamine transfer activity; and triglyceride transfer activity. Involved in circadian rhythm. Acts upstream of or within several processes, including cholesterol homeostasis; lipoprotein transport; and low-density lipoprotein particle remodeling. Located in endoplasmic reticulum. Is expressed in several structures, including gut; liver; placenta; septum transversum hepatic component; and yolk sac. Human ortholog(s) of this gene implicated in several diseases, including abetalipoproteinemia; familial hypercholesterolemia; hyperinsulinism; metabolic dysfunction-associated steatotic liver disease; and obesity. Orthologous to human MTTP (microsomal triglyceride transfer protein). [provided by Alliance of Genome Resources, Apr 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 Mttp often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
