Transcription factor atf3 links host adaptive response to breast cancer metastasis
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, it is presumed, 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.
ATF-3 is induced upon physiological stress in various tissues. It is also a marker of regeneration following injury of dorsal root ganglion neurons in Pain Research.
ATF3 has been shown to interact with:
