| Catalytic Activity | Acyl-CoA + 1-acyl-sn-glycero-3-phosphocholine = CoA + 1,2-diacyl-sn-glycero-3-phosphocholine. |
| Catalytic Activity | Acyl-CoA + 1-acyl-sn-glycero-3- phosphoethanolamine = CoA + 1,2-diacyl-sn-glycero-3- phosphoethanolamine. |
| Catalytic Activity | Acyl-CoA + 1-acyl-sn-glycerol 3-phosphate = CoA + 1,2-diacyl-sn-glycerol 3-phosphate. |
| Function | Membrane-bound O-acyltransferase that mediates the incorporation of unsaturated acyl chains into the sn-2 position of phospholipids. Preferentially acylates lysophosphocholine, but also lysophosphoethanolamine and lysophosphatidylglycerol. {ECO:0000269|PubMed:17652094, ECO:0000269|PubMed:17675291, ECO:0000269|PubMed:17726007, ECO:0000269|PubMed:17996202}. |
| Similarity | Belongs to the membrane-bound acyltransferase family. {ECO:0000305}. |
| Subcellular Location | Endoplasmic reticulum membrane; Multi-pass membrane protein. Microsome membrane; Multi-pass membrane protein. |
