Functional Description ? help Back to Top
Source Description
TAIREncodes zinc finger protein. mRNA levels are upregulated in response to ABA, high salt, and mild dessication. The protein is localized to the nucleus and acts as a transcriptional repressor.
UniProtTranscriptional repressor involved in the inhibition of plant growth under abiotic stress conditions. Can repress the expression of various genes, including osmotic stress and abscisic acid-repressive genes and auxin-inducible genes, by binding to their promoter regions in a DNA sequence-specific manner. Acts as a negative regulator of abscisic acid (ABA) signaling during seed germination. Probably involved in jasmonate (JA) early signaling response. May regulate the expression of the JA biosynthesis gene LOX3 and control the expression of TIFY10A/JAZ1, a key repressor in the JA signaling cascade. May act as a positive regulator of leaf senescence. Has been identified as a suppressor of the deficiency of yeast snf4 mutant to grow on non-fermentable carbon source. {ECO:0000269|PubMed:10929106, ECO:0000269|PubMed:15333755, ECO:0000269|PubMed:18216250, ECO:0000269|PubMed:20619483, ECO:0000269|PubMed:21852415, ECO:0000269|PubMed:22709441}.
