Background:
Transcription factor that possesses transactivation activity in yeast (PubMed:17604002, PubMed:21055780, PubMed:18236009).Involved in abscisic acid (ABA) signaling pathway. Binds to the G-box motif 5'-CACGTG-3' of TRAB1 gene promoter (PubMed:17604002).Involved in the regulation of pollen maturation. May act as negative regulator of salt stress response (PubMed:18236009).Together with PYL5, PP2C30 and SAPK2, is part of an ABA signaling unit that modulates seed germination and early seedling growth (PubMed:22071266).
