Comments
Comment typeDescription
Alternative ProductsEvent=Alternative splicing; Named isoforms=2; Name=1; IsoId=Q9LY09-1; Sequence=Displayed; Name=2; IsoId=Q9LY09-2; Sequence=VSP_044417, VSP_044418; Note=Derived from EST data. No experimental confirmation available.;
Developmental StageMostly expressed in anthers at the later stage of flower development. {ECO:0000269|PubMed:8220457}.
Disruption PhenotypeDelayed pollen hydration and impaired competitive ability due to a failure to interact with the stigma. {ECO:0000269|PubMed:10655594, ECO:0000269|PubMed:20033440}.
FunctionLipid-binding oleosin pollen coat protein required to mediate pollen recognition by stigma cells and subsequent pollen hydration. {ECO:0000269|PubMed:10655594, ECO:0000269|PubMed:20033440}.
SimilarityBelongs to the oleosin family. {ECO:0000305}.
Subcellular LocationSecreted, extracellular space, extracellular matrix, pollen coat. Lipid droplet {ECO:0000250}. Membrane; Multi- pass membrane protein. Note=Surface of oil bodies. Oleosins exist at a monolayer lipid/water interface (By similarity). {ECO:0000250}.
Tissue SpecificityFlower specific, especially in pollen (at protein level). {ECO:0000269|PubMed:10655594, ECO:0000269|PubMed:11431566, ECO:0000269|PubMed:8220457}.
