activating transcription factors

Summary

Summary: Activating transcription factors were originally identified as DNA-BINDING PROTEINS that interact with early promoters from ADENOVIRUSES. They are a family of basic leucine zipper transcription factors that bind to the consensus site TGACGTCA of the cyclic AMP response element, and are closely related to CYCLIC AMP-RESPONSIVE DNA-BINDING PROTEIN.
