ATF2

Usage and Biology

ATF2 belongs to the ATF/CREB family and regulates genes involved in cell growth, stress responses and apoptosis. The ATF-2 protein is DNA-binding that binds to cyclic AMP-response elements (CREs), thereby forming a homodimer or heterodimer with c-Jun. It then stimulates CRE-dependent transcription (Kawasaki et al. , 2000)

We employed ATF2 as a transcription factor in our cell-based beta-lactam-sensor, which in contrast to CcpA (K5317014) or GraR (K5317015) originates from an eukaryotic background, to transfer the PknB-detected signal into reporter gene expression.

Cloning

Theoretical Part Design

The ATF2 gene was synthesized, and the gene sequence was explicity chose from its cDNA to exclude intons and shorten the gene sequence inserted into the final plasmid for characterization (K5317021).

Characterization

The functionality of ATF2 in our cell-based sensor was assessed by analysing its general expression after transfection in HEK293T cells and assessing its localization by fusion with the reporter gene mRuby2 (K5317001). For results please visit the registry entry K5317021.
