  • 产品描述：

    A cDNA sequence coding for full-length human cyclic AMP-dependent transcription factor ATF2 was inserted a 6xHis-SUMO-tag at the N-terminus and then expressed in E.coli. The resulting protein consists of 1-505aa of human ATF2 and has a calculated molecular weight of 70.5 kDa. Its purity is over 90% determined by SDS-PAGE. Under reducing conditions, the gel presented a molecular mass band of about 73 kDa. Glycosylation contributes to the slightly higher molecular mass. This recombinant ATF2 protein may be used for specific antibody production or in the studies of ATF2-related transcription.

    Activating transcription factor 2 (ATF2) is a member of the activating protein-1 (AP1) transcription factor family that regulates gene expression through homo- or hetero-dimerization with other AP1 transcription factors. ATF2 is also a vital mediator of mammalian cell responses to various stimuli, including stress. Alteration of ATF2 expression and localization has also been associated with the pathology, progression, and chemoresistance of extramammary Paget's disease, as well as in prostate and head and neck squamous cancers.

靶点详情

  • 功能：
    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.

  • 亚细胞定位：
    Nucleus. Cytoplasm. Mitochondrion outer membrane. Note=Shuttles between the cytoplasm and the nucleus and heterodimerization with JUN is essential for the nuclear localization. Localization to the cytoplasm is observed under conditions of cellular stress and in disease states. Localizes at the mitochondrial outer membrane in response to genotoxic stress. Phosphorylation at Thr-52 is required for its nuclear localization and negatively regulates its mitochondrial localization. Co-localizes with the MRN complex in the IR-induced foci (IRIF).
