General annotation (Comments)

Function

May transfer the acyl-group from acyl-coA to the sn-1 position of glycerol-3-phosphate, an essential step in glycerolipid biosynthesis. Also transfers the acyl-group from acyl-coA to the sn-2 position of 1-acyl-sn-glycerol-3-phosphate (lysophosphatidic acid, or LPA), forming 1,2-diacyl-sn-glycerol-3-phosphate (phosphatidic acid, or PA). Ref.3

Catalytic activity

Acyl-CoA + sn-glycerol 3-phosphate = CoA + 1-acyl-sn-glycerol 3-phosphate.

Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.

Pathway

Glycerolipid metabolism; triacylglycerol biosynthesis.

Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 1/3.

Subcellular location

Endoplasmic reticulum membrane; Multi-pass membrane protein Ref.3.

Tissue specificity

Most abundant in epididymal fat, followed by small intestine, brown adipose tissue, kidney, heart and colon. Ref.3

Induction

During adipocyte differentiation. Ref.3

Domain

The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate By similarity.

Sequence similarities

Belongs to the 1-acyl-sn-glycerol-3-phosphate acyltransferase family.

Caution

Despite its name, the human ortholog of this protein appears to lack measurable glycerol-3-phosphate acyltransferase activity under some conditions (PMID:19318427).
