Gene Gene information from NCBI Gene database.
Entrez ID 4547
Gene name Microsomal triglyceride transfer protein
Gene symbol MTTP
Synonyms (NCBI Gene)
ABLMTP
Chromosome 4
Chromosome location 4q23
Summary MTP encodes the large subunit of the heterodimeric microsomal triglyceride transfer protein. Protein disulfide isomerase (PDI) completes the heterodimeric microsomal triglyceride transfer protein, which has been shown to play a central role in lipoprotein
