Scarb1 Gene Summary [Mouse]
Enables amyloid-beta binding activity; apolipoprotein binding activity; and high-density lipoprotein particle binding activity. Involved in several processes, including cholesterol homeostasis; cholesterol transport; and regulation of lipid metabolic process. Acts upstream of or within several processes, including cholesterol catabolic process; endothelial cell proliferation; and intestinal lipid absorption. Located in caveola; cell surface; and cytoplasm. Is expressed in several structures, including alimentary system; brain; early conceptus; hemolymphoid system gland; and reproductive system. Orthologous to human SCARB1 (scavenger receptor class B member 1). [provided by Alliance of Genome Resources, Jul 2025]
