General annotation (Comments)

Function	Aux/IAA proteins are short-lived transcriptional factors that function as repressors of early auxin response genes at low auxin concentrations By similarity.
Subunit structure	Homo- and heterodimers By similarity.
Subcellular location	Nucleus By similarity.
Tissue specificity	Highly expressed in flowers. Ref.3
Induction	By auxin. Ref.3
Sequence similarities	Belongs to the Aux/IAA family. Contains 1 Aux/IAA-ARF domain.
