Comment typeDescription
Developmental StageExpressed throughout anther development. {ECO:0000269|PubMed:23602096}.
FunctionProbably involved in light/cold stress-related jasmonate (JA) biosynthesis. Contributes to the protection of photosystem II (PSII) against light stress. {ECO:0000269|PubMed:16571665, ECO:0000269|PubMed:19906042}.
InductionUp-regulated by abscisic acid. {ECO:0000269|PubMed:16571665}.
InteractionO04719:ABI2; NbExp=5; IntAct=EBI-962363, EBI-537680;
MiscellaneousSimultaneous down-regulation of PAP1, PAP2 and PAP3 leads to impaired long-term acclimation to environmental constraint, namely photooxidative stress imposed by high light combined with cold. {ECO:0000305|PubMed:19906042}.
SimilarityBelongs to the PAP/fibrillin family. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast, plastoglobule. Plastid, chloroplast thylakoid. Note=Located in the elaioplast, a tapetum-specific plastidial lipid organelle.
SubunitInteracts (via N-terminus) with ABI2. {ECO:0000269|PubMed:16571665}.
Tissue SpecificityExpressed in flower buds. Detected in tapetal cells, endothecium and connective in anthers and in subepidermal cells in filaments. {ECO:0000269|PubMed:23602096}.
