Auxin-responsive protein IAA17

Gene

IAA17

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Aux/IAA proteins are short-lived transcriptional factors that function as repressors of early auxin response genes at low auxin concentrations. Repression is thought to result from the interaction with auxin response factors (ARFs), proteins that bind to the auxin-responsive promoter element (AuxRE). Formation of heterodimers with ARF proteins may alter their ability to modulate early auxin response genes expression.1 Publication

Miscellaneous

Increased auxin response of mutants axr3-1 and axr3-3 may result from an increased stability of AXR3.

Motifi14 – 18EAR-like (transcriptional repression)5

Domaini

The N-terminal half of the protein contains two conserved domains I and II. Domain I includes a slightly degenerated ERF-associated amphiphilic repression (EAR) motif which seems to be involved in the activity of transcriptional repression. Domain II is required for the correct degradation of the protein through the SCF-mediated ubiquitin-proteasome pathway. Interactions between Aux/IAA proteins and auxin response factors (ARFs) occur through their C-terminal dimerization domains III and IV.
