General annotation (Comments)

Function	Lysophosphatidic acid acyltransferase which functions in phosphatidic acid biosynthesis. May regulate the cellular storage of triacylglycerol through activation of the phospholipase PNPLA2. Involved in keratinocyte differentiation By similarity.
Catalytic activity	Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate.
Subunit structure	Interacts with ADRP, PLIN and PNPLA2 By similarity.
Subcellular location	Cytoplasm By similarity. Lipid droplet By similarity. Note: Colocalized with PLIN and ADRP on the surface of lipid droplets. The localization is dependent upon the metabolic status of the adipocytes and the activity of PKA By similarity.
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 peptidase S33 family. ABHD4/ABHD5 subfamily.
