Application Abreviews Notes
WB 1/1000 - 1/10000. Predicted molecular weight: 22 kDa.
IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function

      Promotes caspase-mediated apoptosis. This proapoptotic activity is mediated predominantly through the activation of caspase-9. May be a component of the inflammasome, a protein complex which also includes NALP2, CARD8 and CASP1 and whose function would be the activation of proinflammatory caspases.
    • Tissue specificity

      Widely expressed at low levels. Detected in peripheral blood leukocytes, lung, small intestine, spleen, thymus, colon and at lower levels in placenta, liver and kidney. Very low expression in skeletal muscle, heart and brain. Detected in the leukemia cell lines HL-60 and U937, but not in Jurkat T-cell lymphoma and Daudi Burkitt's lymphoma. Detected in the melanoma cell line WM35, but not in WM793. Not detected in HeLa cervical carcinoma cells and Molt 4 lymphocytic leukemia cells.
    • Sequence similarities

      Contains 1 CARD domain.
      Contains 1 DAPIN domain.
    • Domain

      Interacts with CIAS1/PYPAF1 and PYDC1 via the DAPIN domain.
    • Post-translational

    • Cellular localization

      Cytoplasm. Upstream of caspase activation, a redistribution from the cytoplasm to the aggregates occurs. These appear as hollow, perinuclear spherical, ball-like structures.

      Unpurified ab151700 was shown to specifically react with TMS1/ASC when TMS1/ASC knockout samples were used. Wild-type and TMS1/ASC knockout samples were subjected to SDS-PAGE. Unpurified ab151700 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
