Human Gene ATF2 (ENST00000409833.5) Description and Page Index
Description: Homo sapiens activating transcription factor 2 (ATF2), transcript variant 6, mRNA. (from RefSeq NM_001256094) RefSeq Summary (NM_001256094): This gene encodes a transcription factor that is a member of the leucine zipper family of DNA binding proteins. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions This protein binds to the cAMP-responsive element (CRE), an octameric palindrome. It forms a homodimer or a heterodimer with c-Jun and stimulates CRE-dependent transcription. This protein is also a histone acetyltransferase (HAT) that specifically acetylates histones H2B and H4 in vitro; thus it may represent a class of sequence-specific factors that activate transcription by direct effects on chromatin components. The encoded protein may also be involved in cell's DNA damage response independent of its role in transcriptional regulation. Several alternatively spliced transcript variants have been found for this gene [provided by RefSeq, Jan 2014].

ID:ATF2_HUMAN DESCRIPTION: RecName: Full=Cyclic AMP-dependent transcription factor ATF-2; Short=cAMP-dependent transcription factor ATF-2; AltName: Full=Activating transcription factor 2; AltName: Full=Cyclic AMP-responsive element-binding protein 2; Short=CREB-2; Short=cAMP-responsive element-binding protein 2; AltName: Full=HB16; AltName: Full=cAMP response element-binding protein CRE-BP1; FUNCTION: Transcriptional activator, probably constitutive, which binds to the cAMP-responsive element (CRE) (consensus: 5'- GTGACGT[AC][AG]-3'), a sequence present in many viral and cellular promoters. Interaction with JUN redirects JUN to bind to CRES preferentially over the 12-O-tetradecanoylphorbol-13-acetate response elements (TRES) as part of an ATF2/JUN complex. SUBUNIT: Binds DNA as a dimer and can form a homodimer in the absence of DNA. Can form a heterodimer with JUN. Interacts with SMAD3 and SMAD4. Binds through its N-terminal region to UTF1 which acts as a coactivator of ATF2 transcriptional activity. INTERACTION: P01100:FOS; NbExp=4; IntAct=EBI-1170906, EBI-852851; P05412:JUN; NbExp=4; IntAct=EBI-1170906, EBI-852823; Q15532:SS18; NbExp=2; IntAct=EBI-1170906, EBI-2560599; A4PIW0:SYT-SSX2; NbExp=11; IntAct=EBI-1170906, EBI-6050533; Q99986:VRK1; NbExp=5; IntAct=EBI-1170906, EBI-1769146; SUBCELLULAR LOCATION: Nucleus. TISSUE SPECIFICITY: Abundant expression seen in the brain. PTM: Phosphorylation of Thr-69 by MAPK14 and MAPK11, and at Thr-71 by MAPK1/ERK2, MAPK3/ERK1, MAPK11, MAPK12 and MAPK14 in response to external stimulus like insulin causes increased transcriptional activity. Phosphorylated by PLK3 following hyperosmotic stress. Also phosphorylated and activated by JNK and CaMK4. SIMILARITY: Belongs to the bZIP family. ATF subfamily. SIMILARITY: Contains 1 bZIP (basic-leucine zipper) domain. SIMILARITY: Contains 1 C2H2-type zinc finger. CAUTION: It is uncertain whether Met-1 or Met-19 is the initiator.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.
ModBase Predicted Comparative 3D Structure on P15336
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
