The CREB-CREM transcription factors are the main gene regulatory effectors of the cAMP signaling pathway. The investigations of this family of transcription factors had a profound impact on the understanding of signaling-induced gene transcription. Here we discuss some key aspects of the underlying biology, review transcriptional activation by CREB proteins through transcription cofactors and present...
The Vβ 8.1 promoter is regulated by T-cell-specific and ubiquitous transcription factors, which bind immediately upstream of and inside the core promoter region. The various Vβ promoters contain two conserved elements, a cAMP responsive element (CRE) located upstream of the core promoter and a basal initiator flanked by two regulatory motifs. Here we have studied the interplay between the distal enhancer...
