Protein
Auxin-responsive protein IAA20
Organism
Arabidopsis thaliana
Function
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.
Similarity
Belongs to the Aux/IAA family.
