Target

  • Function
    Transcription factor that acts during endoplasmic reticulum stress by activating unfolded protein response target genes. Binds DNA on the 5'-CCAC[GA]-3'half of the ER stress response element (ERSE) (5'-CCAAT-N(9)-CCAC[GA]-3') and of ERSE II (5'-ATTGG-N-CCACG-3'). Binding to ERSE requires binding of NF-Y to ERSE. Could also be involved in activation of transcription by the serum response factor.
  • Tissue specificity
    Ubiquitous.
  • Sequence similarities
    Belongs to the bZIP family. ATF subfamily.
    Contains 1 bZIP domain.
  • Domain
    The basic domain functions as a nuclear localization signal.
    The basic leucine-zipper domain is sufficient for association with the NF-Y trimer and binding to ERSE.
  • Post-translational
    modifications
    During unfolded protein response an approximative 50 kDa fragment containing the cytoplasmic transcription factor domain is released by proteolysis. The cleavage seems to be performed sequentially by site-1 and site-2 proteases.
    N-glycosylated. The glycosylation status may serve as a sensor for ER homeostasis, resulting in ATF6 activation to trigger the unfolded protein response (UPR).
    Phosphorylated in vitro by MAPK14/P38MAPK.
  • Cellular localization
    Endoplasmic reticulum membrane and Nucleus. Under ER stress the cleaved N-terminal cytoplasmic domain translocates into the nucleus.

  • Predicted band size : 75 kDa

    Lane 1: Wild type HAP1 whole cell lysate (50 µg)
    Lane 2: ATF6 knockout  HAP1 whole cell lysate (50 µg)
    Lanes 1 - 2: Merged signal (red and green). Green - ab122897 observed at 95 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab122897 was shown to specifically recact with ATF6 in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when ATF6 knockout samples were used. Wild-type and ATF6 knockout samples were subjected to SDS-PAGE. Ab122897 and ab181602 (Rabbit anti GAPDH loading control) were incubated overnight at 4°C at 1/500 dilution and 1/10,000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed (ab216777) secondary antibodies at 1/10,000 dilution for 1hr at room temperature before imaging.

  • Immunofluorescent analysis of HeLa cells using ab122897 at a dilution of 1/100. The cells were fixed with paraformaldehyde. The secondary antibody was an Alexa Fluor® 488 conjugated goat anti-mouse IgG at a dilution of 1/1000. The antibody staining is shown in the top panel, and the merged image with DAPI counter-staining is shown in the lower panel.

  • All lanes : Anti-ATF6 antibody [1-7] (ab122897) at 1/500 dilution

    Lane 1 : 293T cell lysate: control
    Lane 2 : 293T cell lysate: treated with 2 µg/ml tunicamycin for 7 hours
    Lane 3 : 293T cell lysate: treated with 1mM DTT for 1 hour.

    Lane 5 : HeLa S3 Tet-off cell lysate: treated with 1mM DTT for 1 hour.


    Predicted band size : 75 kDa
    Conversion of precursors pATF6(P) to pATF6(N) in DTT- or tunicamycin-treated cells. ATF6 is constitutively expressed as pATF6a(P) (~90-kDa protein), and converted to pATF6a(N) (>50-kDa protein) in ER-stressed cells.

    Conversion of precursors pATF6(P) to pATF6(N) in DTT- or tunicamycin-treated cells. ATF6 is constitutively expressed as pATF6a(P) (~90-kDa protein), and converted to pATF6a(N) (>50-kDa protein) in ER-stressed cells.
  • ATF6 was detected by Western blot (Input; lanes 1, 2, 7, and 8) using ab122897 (No. 1-7). After immunoprecipitation (IP) with non-related IgG (IP; lanes 3, 4, 9, and 10) or ab122897 (No. 1-7) (IP; lanes 5, 6, 11, and 12), samples were subjected to SDS-PAGE and analyzed by Western blot using ab122897 (No. 1-7) and anti-mouse IgG antibody (light chain specific).
