Enables cholesterol transfer activity; phosphatidylethanolamine transfer activity; and triglyceride transfer activity. Acts upstream of or within several processes, including cholesterol homeostasis; lipoprotein transport; and low-density lipoprotein particle remodeling. Located in Golgi apparatus and endoplasmic reticulum. Is expressed in gut; liver; placenta; septum transversum hepatic component; and yolk sac. Human ortholog(s) of this gene implicated in several diseases, including abdominal obesity-metabolic syndrome 1; abetalipoproteinemia; familial hypercholesterolemia; hyperinsulinism; and obesity. Orthologous to human MTTP (microsomal triglyceride transfer protein). [provided by Alliance of Genome Resources, Apr 2022]
