Protein attributes

Sequence length	199 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

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. Expressed at low levels in roots and shoots. Ref.3
Induction	By auxin. Ref.3
Sequence similarities	Belongs to the Aux/IAA family. Contains 1 Aux/IAA-ARF domain.
