Comments
Comment typeDescription
DomainThe F-box is necessary for the interaction with SKP1. {ECO:0000250}.
FunctionConfers sensitivity to the virulent bacterial pathogen P.syringae (By similarity). Component of SCF(ASK-cullin-F-box) E3 ubiquitin ligase complexes, which may mediate the ubiquitination and subsequent proteasomal degradation of target proteins. Auxin receptor that mediates Aux/IAA proteins proteasomal degradation and auxin-regulated transcription. Involved in embryogenesis regulation by auxin. {ECO:0000250, ECO:0000269|PubMed:15917797, ECO:0000269|PubMed:15992545}.
InductionRepressed by miR393a (microRNA) in response to flg-22 (flagellin-derived peptide 22). {ECO:0000269|PubMed:16627744}.
PathwayProtein modification; protein ubiquitination.
SimilarityContains 1 F-box domain. {ECO:0000305}.
Subcellular LocationNucleus {ECO:0000269|PubMed:15992545}.
SubunitPart of a SCF (SKP1-cullin-F-box) protein ligase complex. Interacts with CUL1 and SKP1A/ASK1. Interacts with Aux/IAA proteins (IAA7 and IAA12) in an auxin-dependent manner. {ECO:0000269|PubMed:15992545}.
Tissue SpecificityUbiquitous, with higher levels in flowers. {ECO:0000269|PubMed:15992545}.
