Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor involved in cold-regulation of CBF genes and in the development of freezing tolerance. May be part of a complex network of transcription factors controlling the expression of CBF genes and other genes in response to cold stress. Binds to the MYB recognition sequences in the promoters of CBF1, CBF2 and CBF3 genes (PubMed:17015446). Involved in drought and salt tolerance. May enhance expression levels of genes involved in abscisic acid (ABA) biosynthesis and signaling, as well as those encoding stress-protective proteins (PubMed:19161942). {ECO:0000269\|PubMed:17015446, ECO:0000269\|PubMed:19161942}.
