General annotation (Comments)

Function	Aux/IAA proteins are short-lived transcriptional factors that function as repressor 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. Ref.7
Subunit structure	Homo and heterodimers. Interacts with the auxin response factors ARF1 and IAA24.
Subcellular location	Nucleus.
Induction	By auxin.
Domain	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. Ref.8
Post-translational modification	Phosphorylated by phytochrome A in vitro. Ref.6
Miscellaneous	Increased auxin response of mutants axr3-1 and axr3-3 may result form an increased stability of AXR3.
Sequence similarities	Belongs to the Aux/IAA family. Contains 1 Aux/IAA-ARF domain.
