Recombinant Human ATF3 protein, His-SUMO-tagged
Recombinant Human ATF3, fused with His-SUMO tag, was expressed in E. coli.
This protein binds the cAMP response element (CRE) (consensus: 5"-GTGACGT[AC][AG]-3"), a sequence present in many viral and cellular promoters. Represses transcription from promoters with ATF sites. It may repress transcription by stabilizing the binding of inhibitory cofactors at the promoter. Isoform 2 activates transcription presumably by sequestering inhibitory cofactors away from the promoters.
