Summary

MBOAT7 (membrane bound acylglycerophosphatidylinositol O-acyltransferase MBOAT7, HGNC:15505) is a protein-coding gene on chromosome 19q13.42, encoding Membrane-bound acylglycerophosphatidylinositol O-acyltransferase MBOAT7 (Q96N66). Acyltransferase which catalyzes the transfer of an acyl group from an acyl-CoA to a lysophosphatidylinositol (1-acylglycerophosphatidylinositol or LPI) leading to the production of a phosphatidylinositol (1,2-diacyl-sn-glycero-3-phosphoinositol or PI) and participates in the rea….

This gene encodes a member of the membrane-bound O-acyltransferases family of integral membrane proteins that have acyltransferase activity. The encoded protein is a lysophosphatidylinositol acyltransferase that has specificity for arachidonoyl-CoA as an acyl donor. This protein is involved in the reacylation of phospholipids as part of the phospholipid remodeling pathway known as the Land cycle. Alternative splicing results in multiple transcript variants.

Function. Acyltransferase which catalyzes the transfer of an acyl group from an acyl-CoA to a lysophosphatidylinositol (1-acylglycerophosphatidylinositol or LPI) leading to the production of a phosphatidylinositol (1,2-diacyl-sn-glycero-3-phosphoinositol or PI) and participates in the reacylation step of the phospholipid remodeling pathway also known as the Lands cycle. Prefers arachidonoyl-CoA as the acyl donor, thus contributing to the regulation of free levels arachidonic acid in cell. In liver, participates in the regulation of triglyceride metabolism through the phosphatidylinositol acyl-chain remodeling regulation.

Subunit / interactions. Interacts with SPTSSA; the interaction facilitates MBOAT7 location to mitochondria-associated membranes (MAMs).

Subcellular location. Endoplasmic reticulum membrane.

Tissue specificity. Overexpressed in metastatic breast and bladder carcinomas relative to normal breast epithelium and urothelium.

Disease relevance. Intellectual developmental disorder, autosomal recessive 57 (MRT57) [MIM:617188] A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. MRT57 patients have moderate to severe intellectual disability, and delayed psychomotor development with poor or absent speech. Some patients manifest seizures and autistic features. The disease is caused by variants affecting the gene represented in this entry.

Activity regulation. Activity is inhibited by thimerosal.

Pathway. Lipid metabolism; phospholipid metabolism.

Similarity. Belongs to the membrane-bound acyltransferase family.

Enriched among interaction partners

Reactome pathways and GO biological processes over-represented among this gene’s 172 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
