Microsomal triglyceride transfer protein: a protein complex required for the assembly of lipoprotein particles.
The mechanism of assembly of lipoprotein particles in the lumen of the endoplasmic reticulum is an important but poorly understood biological problem. A knowledge of this process is of great practical importance because possession of elevated levels of lipoproteins is one of the major risk factors for the development of atherosclerosis. This review describes a major advance in the delineation of the mechanisms involved in the assembly and secretion of apolipoprotein-B-containing lipoproteins: the demonstration of a requirement for microsomal triglyceride transfer protein.
