Alternative Name(s): Activating transcription factor 7 Transcription factor ATF-A

Relevance: Plays important functions in early cell signaling. Binds the cAMP response element (CRE) (consensus: 5'-GTGACGT[AG][AG]-3'), a sequence present in many viral and cellular promoters. Activator of the NF-ELAM1/delta-A site of the E-selectin promoter. Has no intrinsic transcriptional activity, but activates transcription on formation of JUN or FOS heterodimers. Also can bind TRE promoter sequences when heterodimerized with members of the JUN family. Isoform 4 acts as a dominant repressor of the E-selectin/NF-ELAM1/delta-A promoter. Isoform 5 acts as a negative regulator, inhibiting both ATF2 and ATF7 transcriptional activities. It may exert these effects by sequestrating in the cytoplasm the Thr-53 phosphorylating kinase, preventing activation.

Purity: Greater than 90% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer，50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
