Disruption PhenotypeReduction by 40 percents of 18:2 and 18:3 triacylglycerols (TAG) accumulation in seeds. {ECO:0000269|PubMed:19833868, ECO:0000269|PubMed:22932756}.
FunctionFunctions as phosphatidylcholine:diacylglycerol cholinephosphotransferase that catalyzes the transfer of the phosphocholine headgroup from phosphatidylcholine (PC) to diacylglycerol, a major reaction for the transfer of 18:1 into phosphatidylcholine for desaturation and also for the reverse transfer of 18:2 and 18:3 into the triacylglycerols synthesis pathway. {ECO:0000269|PubMed:19833868, ECO:0000269|PubMed:22371508, ECO:0000269|PubMed:22932756}.
Sequence CautionSequence=AAK49592.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
SimilarityBelongs to the phosphatidylcholine:diacylglycerol cholinephosphotransferase family. {ECO:0000305}.
Subcellular LocationMembrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
