    Western blot analysis of extracts from Hela (lane 2(20μg), Hela (lane 3(40μg), using Phospho-ATF2 (Thr71) Antibody. Proteins were transferred to a PVDF membrane and blocked with 5% BSA in TBST for 2 hour at room temperature. The primary antibody and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% BSA in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

Background

  • Function

    ATF2 transcriptional activator which regulates the transcription of various genes, including those involved in anti-apoptosis, cell growth, and DNA damage response. Dependent on its binding partner, binds to CRE (cAMP response element) consensus sequences (5'-TGACGTCA-3') or to AP-1 (activator protein 1) consensus sequences (5'-TGACTCA-3'). In the nucleus, contributes to global transcription and the DNA damage response, in addition to specific transcriptional activities that are related to cell development, proliferation and death. In the cytoplasm, interacts with and perturbs HK1- and VDAC1-containing complexes at the mitochondrial outer membrane, thereby impairing mitochondrial membrane potential, inducing mitochondrial leakage and promoting cell death. The phosphorylated form (mediated by ATM) plays a role in the DNA damage response and is involved in the ionizing radiation (IR)-induced S phase checkpoint control and in the recruitment of the MRN complex into the IR-induced foci (IRIF). Exhibits histone acetyltransferase (HAT) activity which specifically acetylates histones H2B and H4 in vitro. In concert with CUL3 and RBX1, promotes the degradation of KAT5 thereby attenuating its ability to acetylate and activate ATM. Can elicit oncogenic or tumor suppressor activities depending on the tissue or cell type

    P15336 has 8 isomers: P15336-1: 54537 Da (predicted); P15336-2: 35044 Da (predicted); P15336-3: 23050 Da (predicted); P15336-4: 48013 Da (predicted); P15336-5: 52277 Da (predicted); P15336-6: 13149 Da (predicted); P15336-7: 24097 Da (predicted); P15336-8: 15409 Da (predicted).
    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 (PubMed:12110590, PubMed:9430721). Phosphorylated by PLK3 following hyperosmotic stress (PubMed:21098032). Also phosphorylated and activated by JNK and CaMK4 (PubMed:8855261). ATM-mediated phosphorylation at Ser-490 and Ser-498 stimulates its function in DNA damage response (PubMed:15916964). Phosphorylation at Ser-62, Thr-73 and Ser-121 activates its transcriptional activity (PubMed:15105425). Phosphorylation at Thr-69 or Thr-71 enhances acetylation of histones H2B and H4 (PubMed:10821277)

  • Subunit

    Binds DNA as a dimer and can form a homodimer in the absence of DNA. Can form a heterodimer with JUN. Heterodimerization is essential for its transcriptional activity. Interacts with SMAD3 and SMAD4. Interacts with the HK1/VDAC1 complex. Interacts with NBN, MRE11, XPO1, KAT5 and CUL3 (By similarity). Binds through its N-terminal region to UTF1 which acts as a coactivator of ATF2 transcriptional activity
