This protein binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters.
ATF3 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.Activating transcription factor 3 is a member of the mammalian activation transcription factor/cAMP responsive element-binding (CREB) protein family of transcription factors.
Multiple transcript variants encoding two different isoforms have been found for this gene.
The longer isoform represses rather than activates transcription from promoters with ATF binding elements.
The shorter isoform (deltaZip2) lacks the leucine zipper protein-dimerization motif and does not bind to DNA, and it stimulates transcription presumably by sequestering inhibitory co-factors away from the promoter.
It is possible that alternative splicing of the ATF3 gene may be physiologically important in the regulation of target genes.
