Enables several functions, including cholesterol transfer activity; heparin binding activity; and signaling receptor binding activity. Involved in several processes, including cholesterol homeostasis; low-density lipoprotein particle clearance; and low-density lipoprotein particle remodeling. Located in cytosol; endoplasmic reticulum exit site; and neuronal cell body. Part of low-density lipoprotein particle; mature chylomicron; and triglyceride-rich plasma lipoprotein particle. Is active in extracellular space. Implicated in several diseases, including artery disease (multiple); biliary tract cancer (multiple); familial hyperlipidemia (multiple); hypobetalipoproteinemia (multiple); and sickle cell anemia. Biomarker of several diseases, including common bile duct neoplasm; diabetes mellitus (multiple); familial combined hyperlipidemia; hypobetalipoproteinemia; and obesity.
