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}.

Regulation -- Description ? help Back to Top
Source	Description
UniProt	INDUCTION: Induced by salt stress, drought stress and abscisic acid (ABA). Down-regulated by salicylic acid (SA) methyl jasmonate (JA). {ECO:0000269\|PubMed:23660402}.
