ATF4 Antibody

Activating Transcription Factor 4, also know as CREB2, belongs to the large ATF/CREB family of transcription factors which bind DNA via their basic region and dimerize via their leucine zipper domain to form a variety of homo- and heterodimers to regulate gene transcription. Members of this family share significant sequence similarity within a leucine zipper DNA-binding motif and an adjacent basic region. Unlike CREB, which activates transcription from CRE-containing promoters, CREB2/ATF4 functions as a specific repressor of CRE-dependent transcription. The transcriptional repressor activity resides within the C-terminal leucine zipper and basic domain region of the ATF4 protein.
