Summaries for MTTP Gene

Entrez Gene Summary for MTTP Gene

  • 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 assembly. Mutations in MTP can cause abetalipoproteinemia. [provided by RefSeq, Jul 2008]

GeneCards Summary for MTTP Gene

MTTP (Microsomal Triglyceride Transfer Protein) is a Protein Coding gene. Diseases associated with MTTP include Abetalipoproteinemia and Abdominal Obesity-Metabolic Syndrome 1. Among its related pathways are Fat digestion and absorption and Circadian rythm related genes. Gene Ontology (GO) annotations related to this gene include protein heterodimerization activity and lipid transporter activity.
