Source	Description
Uniprot	TISSUE SPECIFICITY: Expressed in chalaza of mature seeds, cotyledons, rosette leaves, cauline leaves, veins of stems, mature siliques, sepals and styles. Expressed at low levels in roots. {ECO:0000269\|PubMed:23660402}.

Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor that acts as positive regulator of abscisic acid (ABA) signaling in response to salt stress. Acts as negative regulator ABI1, ABI2 and PP2CA, which are protein phosphatases 2C acting as negative regulator of ABA signaling. Binds to the DNA specific sequence and core element 5'-ACGT-3' found in the promoters of ABI1 and PP2CA to negatively regulate their expression during ABA-dependent salt stress response. {ECO:0000269\|PubMed:23660402}.
