Activating transcription factor (ATF) is a group of bZIP transcription factors, which act as homodimers or heterodimers with a range of other bZIP factors.[1] First, they have been described as members of the CREB/ATF family,[2] whereas it turned out later that some of them might be more similar to AP-1-like factors such as c-Jun or c-Fos.[3] Some of these ATFs, such as ATF3, ATF4, and ATF6 are known to play a role in stress responses.[4] Another example of ATF function would be ATFx that can suppress apoptosis.[5]

"ATF4 is known to regulate transcription by formation of the dimer complexes with the transcription factors of AP-1, Jun and C/EBP (CCAAT-enhancer binding protein) families (Horiguchi et al., 2012; Kilberg et al., 2009). The dimers bind to hybrid C/EBP-ATF responsive elements (CARE), consisting of two half-sites required for binding of C/EBP and ATF family proteins, respectively (Kilberg et al., 2009). By scanning ADM2 promoter region, we did not find potential ATF4 binding sites at reasonable distances upstream of the transcription start site. However a suitable candidate for ATF4-response element (GTTGCATCA corresponding to the consensus XTTXCATCA (Kilberg et al., 2009)) was found at a distance of 30 bp downstream from the ADM2 translation start codon."[6]

"ATF4 regulates transcription of its target genes through the formation of homodimers or heterooligomers with the transcription factors Jun, AP-1 and C/EBP38,39 that bind to CARE (C/EBP-ATF) responsive elements having the consensus sequence XTTXCATCA (where X = G, A or T).39 In the region from -625 to -618 bp relative to the SESN2 translation start codon (from -228 to -221 bp relative to the transcription start site) we found a candidate sequence for the ATF4 binding site TTTTCATCA."[7]

Human genes

Main article: Human genes

Genes include ATF1, ATF2, ATF3, ATF4, ATF5, ATF6, ATF7, ATFx.

Gene ID: 466 is ATF1 activating transcription factor 1 on 12q13.12: "This gene encodes an activating transcription factor, which belongs to the ATF subfamily and bZIP (basic-region leucine zipper) family. It influences cellular physiologic processes by regulating the expression of downstream target genes, which are related to growth, survival, and other cellular activities. This protein is phosphorylated at serine 63 in its kinase-inducible domain by serine/threonine kinases, cAMP-dependent protein kinase A, calmodulin-dependent protein kinase I/II, mitogen- and stress-activated protein kinase and cyclin-dependent kinase 3 (cdk-3). Its phosphorylation enhances its transactivation and transcriptional activities, and enhances cell transformation. Fusion of this gene and FUS on chromosome 16 or EWSR1 on chromosome 22 induced by translocation generates chimeric proteins in angiomatoid fibrous histiocytoma and clear cell sarcoma. This gene has a pseudogene on chromosome 6."[8]

Consensus sequences

Main article: Consensus sequence gene transcriptions

"The ATF4 binding consensus sequence has been reported as (G/A/C)TT(G/A/T)C(G/A)TCA (38), which matches the ChIP-seq data."[9]

5'-(A/G/T)TT(A/G/T)CATCA-3'[7]

Combined consensus sequences are XTTXCATCA (where X = G, A or T), TTTTCATCA, and (G/A/C)TT(G/A/T)C(G/A)TCA to produce 5'-NTT(A/G/T)C(A/G)TCA-3'.

Hypotheses

Main article: Hypotheses
  1. A1BG has no Activating transcription factor in either promoter.
  2. A1BG is not transcribed by an Activating transcription factor.
  3. Activating transcription factors do not participate in the transcription of A1BG.
