Microsomal triglyceride transfer protein large subunit is a protein that in humans is encoded by the MTTP gene.[1][2]
MTP encodes the large subunit of the heterodimeric microsomal triglyceride transfer protein. Protein disulfide isomerase (PDI) completes the heterodimeric microsomal triaglyceride transfer protein, which has been shown to play a central role in lipoprotein assembly. Mutations in MTP can cause abetalipoproteinemia.[2]
Apolipoprotein B48 on chylomicra and Apolipoprotein B100 on LDL, IDL, and VLDL are important for MTP binding.

Pharmacology
Drugs that inhibit MTTP prevent the assembly of apo B-containing lipoproteins thus inhibiting the synthesis of chylomicrons and VLDL and leading to decrease in plasma levels of LDL-C.
- Lomitapide (Juxtapid) was approved by the US FDA for adjunctive treatment of homozygous familial hypercholesterolemia.
- Dirlotapide (Slentrol) and mitratapide (Yarvitan) are veterinary drugs for the management of obesity in dogs.
