General annotation (Comments)

Function

Confers 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. Ref.5 Ref.6

Pathway

Protein modification; protein ubiquitination.

Subunit structure

Part 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. Ref.5

Subcellular location

Nucleus Ref.5.

Tissue specificity

Ubiquitous, with higher levels in flowers. Ref.5

Induction

Repressed by miR393a (microRNA) in response to flg-22 (flagellin-derived peptide 22). Ref.7

Domain

The F-box is necessary for the interaction with SKP1 By similarity.

Sequence similarities

Contains 1 F-box domain.
