The human ATF and AP1 transcription factors bind to highly related DNA sequences. Their consensus binding sites differ by a single nucleotide, but this single change is crucial in determining factor binding specificity. We have previously identified an AP1 (yAP1) binding activity in yeast. In this report we identify a yeast ATF (yATF) binding activity whose specificity can be distinguished from that of yAP1 by the same crucial nucleotide that distinguishes binding of human ATF and AP1. The ATF binding site can act as an efficient upstream activating sequence in vivo, suggesting that yATF is a transcriptional activator. The yATF DNA-binding complex is phosphorylated and the binding activity of partially purified yATF can be enhanced in vitro by the addition of protein kinase A, indicating that the phosphorylation state of yATF may be important in determining its ability to bind DNA.
