mouse monoclonal IgG1; ATF-1 Antibody (25C10G) is an IgG1 κ mouse monoclonal ATF-1 antibody (also designated ATF1 antibody, activating transcription factor 1 antibody or TREB36 antibody) that detects the ATF-1 protein of mouse, rat and human origin by WB, IP, IF and IHC(P). ATF-1 Antibody (25C10G) is available as both the non-conjugated anti-ATF-1 antibody form, as well as multiple conjugated forms of anti-ATF-1 antibody, including agarose, HRP, PE, FITC and multiple Alexa Fluor® conjugates. Eukaryotic gene transcription is regulated by sequence-specific transcription factors that bind modular cis acting promoter and enhancer elements. The ATF/ CREB transcription factor family binds the palindromic cAMP response element (CRE) octanucleotide TGACGTCA. The ATF/CREB family includes CREB-1, CREB-2 (also designated ATF-4), ATF-1, ATF-2 and ATF-3. This family of proteins contain highly divergent N-terminal domains, but share a C-terminal leucine zipper for dimerization and DNA binding. ATF-1 is shown to play a key role in the induction of NOX1. ATF-1 binds the cAMP response element (CRE) and mediates PKA-induced stimulation of CRE-reporter genes. ATF-2 forms homodimers and heterodimers with c-Jun to initiate CRE-dependent transcription. Phosphorylation of ATF-2 at Thr 69 and Thr 71 by stress-activated kinases is necessary for transcriptional activation. Myc also induces phosphorylation of ATF-2 at Thr 69 and Thr 71 to prolong the half-life of ATF-2. ATF-2 functions as a histone acetyltransferase (HAT) and acetylates Histones H2B and H4 specifically in vitro.
