Target Data

Function Transcription factor that either stimulates or represses gene transcription through binding of different DNA regulatory elements such as cAMP response element (CRE) (consensus
Gene References into Functions
  1. Data suggest that ATF5 is modified by SUMO2/3 at a conserved SUMO-targeting consensus site; this SUMOylation of ATF5 appears to be required for transport of ATF5 to centrosome. (ATF5 = activating transcription factor-5; SUMO = small ubiquitin-like modifier) PMID: 29326161
  2. Study reports that reduced levels of ATF5 in brain of Huntington's disease patients, probably due to its sequestration into the characteristic PolyQ containing neuronal inclusion bodies, correlates with decreased levels of the antiapoptotic protein MCL1, a transcriptional target of ATF5. Also provides evidence of decreased ATF5 being deleterious by rendering neurons more vulnerable to polyQ-induced apoptosis. PMID: 28861715
  3. ATF5 expression can rescue UPR(mt) signaling in atfs-1-deficient worms requiring the same UPR(mt) promoter element identified in C. elegans. Furthermore, mammalian cells require ATF5 to maintain mitochondrial activity during mitochondrial stress and promote organelle recovery. Combined, these data suggest that regulation of the UPR(mt) is conserved from worms to mammals. PMID: 27426517

  6. These results suggest that the hepatic functions of the human iPS-HLCs could be enhanced by ATF5, c/EBPalpha, and PROX1 transduction. PMID: 26679606

  13. N-terminal hydrophobic amino acids play an important role in the regulation of ATF5 protein expression in IL-1beta-mediated immune response and that ATF5 is a negative regulator for IL-1beta-induced expression of SAA1 and SAA2 in HepG2 cells. PMID: 24379400
  14. The 5'-untranslated region regulates ATF5 mRNA stability via nonsense-mediated mRNA decay in response to environmental stress. PMID: 23876217

  16. The evidence suggests a role for ATF5 in the regulation of osteogenic differentiation in adipose-derived stem cells. PMID: 22442021
