Comments
Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q9M8Z7-1; Sequence=Displayed; Name=2; IsoId=Q9M8Z7-2; Sequence=VSP_046337;
Catalytic ActivityUDP-glucose + a sterol = UDP + a sterol 3- beta-D-glucoside.
Disruption PhenotypeReduced growth rates. {ECO:0000269|PubMed:19641030}.
FunctionInvolved in the biosynthesis of sterol glucosides. Catalyzes the synthesis of steryl glycosides (SGs) and acyl steryl glycosides (ASGs) which are the most abundant sterol derivatives in higher plants. Can act on several sterols like sitosterol, campesterol and stigmasterol. Both UGT80A2 and UGT80B1 are required for the normal production of SGs and ASGs in seeds. {ECO:0000269|PubMed:19641030, ECO:0000269|PubMed:21830156}.
Sequence CautionSequence=AAL09737.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
SimilarityBelongs to the glycosyltransferase 28 family. {ECO:0000305}.
Tissue SpecificityExpressed in roots, cauline leaf epidermal cells, stomata, stamen, pollen and around the base of siliques. {ECO:0000269|PubMed:12721858, ECO:0000269|PubMed:19641030}.
