Protein attributes

Sequence length	500 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Esterifies acyl-group from acyl-ACP to the sn-1 position of glycerol-3-phosphate, an essential step in glycerolipid biosynthesis By similarity.
Catalytic activity	Acyl-CoA + sn-glycerol 3-phosphate = CoA + 1-acyl-sn-glycerol 3-phosphate.
Pathway	Phospholipid metabolism; CDP-diacylglycerol biosynthesis; CDP-diacylglycerol from sn-glycerol 3-phosphate: step 1/3.
Subcellular location	Membrane; Multi-pass membrane protein Potential.
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 GPAT/DAPAT family.
Sequence caution	The sequence AAB62826.1 differs from that shown. Reason: Erroneous gene model prediction. Was originally thought to correspond to two different genes At4g00400 and At4g00410. The sequence AAB62827.1 differs from that shown. Reason: Erroneous gene model prediction. Was originally thought to correspond to two different genes At4g00400 and At4g00410. The sequence AAF02784.1 differs from that shown. Reason: Erroneous gene model prediction. Was originally thought to correspond to two different genes At4g00400 and At4g00410. The sequence AAF02785.1 differs from that shown. Reason: Erroneous gene model prediction. Was originally thought to correspond to two different genes At4g00400 and At4g00410. The sequence CAB80798.1 differs from that shown. Reason: Erroneous gene model prediction. Was originally thought to correspond to two different genes At4g00400 and At4g00410. The sequence CAB80799.1 differs from that shown. Reason: Erroneous gene model prediction. Was originally thought to correspond to two different genes At4g00400 and At4g00410.
