Comments
Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q9SJI7-1; Sequence=Displayed; Name=2; IsoId=Q9SJI7-2; Sequence=VSP_041299, VSP_041300;
Disruption PhenotypeEnhanced tolerance to UV-B stress but not osmotic stress. Impaired PR-1 accumulation in response to UV-B. {ECO:0000269|PubMed:15181214}.
FunctionAcylhydrolase that catalyzes the hydrolysis of phosphatidylcholine (PC) at the sn-1 position. High activity toward PC, medium activity toward monogalactosyldiacylglycerol (MGDG) and low activity toward triacylglycerol (TAG). Confers sensitivity to UV-B radiation probably by deesterifying membrane phospholipids. {ECO:0000269|PubMed:15181214}.
InductionStrongly induced in response to sublethal levels of UV- B radiation. Down-regulated as the leaves senesce. {ECO:0000269|PubMed:15181214}.
SimilarityBelongs to the AB hydrolase superfamily. Lipase family. {ECO:0000305}.
Subcellular LocationCytoplasm {ECO:0000269|PubMed:15181214}.
Tissue SpecificityExpressed in leaves, stems, flowers and siliques, and, at low levels, in seeds and roots (at protein level). {ECO:0000269|PubMed:15181214}.
