CC -!- FUNCTION: Aux/IAA proteins are short-lived transcriptional factors that
CC function as repressors of early auxin response genes at low auxin
CC concentrations. Repression is thought to result from the interaction
CC with auxin response factors (ARFs), proteins that bind to the auxin-
CC responsive promoter element (AuxRE). Formation of heterodimers with ARF
CC proteins may alter their ability to modulate early auxin response genes
CC expression. {ECO:0000269|PubMed:12036262}.
CC -!- SUBUNIT: Homodimers and heterodimers. Interacts with the auxin-
CC responsive protein IAA2. Interacts with TPL.
CC {ECO:0000269|PubMed:18258861}.

CC -!- SUBCELLULAR LOCATION: Nucleus.
CC -!- TISSUE SPECIFICITY: Preferentially expressed in stems, leaves and
CC flowers. {ECO:0000269|PubMed:7658471}.
CC -!- INDUCTION: By auxin. {ECO:0000269|PubMed:7658471}.
CC -!- DOMAIN: The N-terminal half of the protein contains two conserved
CC domains I and II. Domain I includes a slightly degenerated ERF-
CC associated amphiphilic repression (EAR) motif which seems to be
CC involved in the activity of transcriptional repression. Domain II is
CC required for the correct degradation of the protein through the SCF-
CC mediated ubiquitin-proteasome pathway. Interactions between Aux/IAA
CC proteins and auxin response factors (ARFs) occur through their C-
CC terminal dimerization domains III and IV.
CC -!- PTM: Phosphorylated by phytochrome A in vitro.
CC {ECO:0000269|PubMed:11115889}.
CC -!- SIMILARITY: Belongs to the Aux/IAA family. {ECO:0000305}.
