Identification and characterization of dual inhibitors for phospholipid transfer protein and microsomal triglyceride transfer protein.
Phospholipid transfer protein (PLTP) plays an important role in atherogenesis and lipoprotein metabolism. PLTP exerts its functions intracellularly and extracellularly. Both PLTP and microsomal triglyceride transfer protein (MTP) have been shown to regulate the secretion of apolipoprotein B (apoB) in hepatocytes. We have previously reported the characterization of inhibitors that selectively in...
متن کاملLoss of both phospholipid and triglyceride transfer activities of microsomal triglyceride transfer protein in abetalipoproteinemia.
Mutations in microsomal triglyceride transfer protein (MTP) cause abetalipoproteinemia (ABL), characterized by the absence of plasma apoB-containing lipoproteins. In this study, we characterized the effects of various MTP missense mutations found in ABL patients with respect to their expression, subcellular location, and interaction with protein disulfide isomerase (PDI). In addition, we charac...
متن کاملMicrosomal triglyceride transfer protein: a multifunctional protein.
Microsomal triglyceride transfer protein (MTP) is a heterodimeric protein that transfers neutral lipids between membranes in vitro. Absence of this lipid transfer activity in the microsomes of abetalipoproteinemia patients established its pivotal function in lipoprotein assembly. Recent studies indicate that the lipid transfer activity is involved in importing triglycerides into the lumen of th...
متن کاملMultiple functions of microsomal triglyceride transfer protein
Microsomal triglyceride transfer protein (MTP) was first identified as a major cellular protein capable of transferring neutral lipids between membrane vesicles. Its role as an essential chaperone for the biosynthesis of apolipoprotein B (apoB)-containing triglyceride-rich lipoproteins was established after the realization that abetalipoproteinemia patients carry mutations in the MTTP gene resu...
متن کاملIdentification of a Novel Transcript and Regulatory Mechanism for Microsomal Triglyceride Transfer Protein
Microsomal triglyceride transfer protein (MTP) is essential for the assembly of triglyceride-rich apolipoprotein B-containing lipoproteins. Previous studies in our laboratory identified a novel splice variant of MTP in mice that we named MTP-B. MTP-B has a unique first exon (1B) located 2.7 kB upstream of the first exon (1A) for canonical MTP (MTP-A). The two mature isoforms, though nearly iden...
