Comments
Comment typeDescription
Developmental StageIncreased expression during seed development and as pollen development proceeded from uninucleate microspore to mature pollen. {ECO:0000269|PubMed:15535861}.
Disruption PhenotypeNo visible phenotype. {ECO:0000269|PubMed:19923239}.
FunctionInvolved in the esterification of cycloartenol. Not implicated in the formation of sterol esters in flowers or during seed maturation. Has a substrate preference toward saturated fatty acyl donors (16:0 > 18:0 > 16:1 > 18:1). Does not require triacyglycerols (TAGs) as a fatty acyl donor, and is unable to acylate diacylglycerol to produce TAG. {ECO:0000269|PubMed:17885082, ECO:0000269|PubMed:19923239}.
InteractionP34791:CYP20-3; NbExp=3; IntAct=EBI-2025397, EBI-449385;
SimilarityBelongs to the wax synthase family. {ECO:0000305}.
Subcellular LocationMembrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
