Application Abreviews Notes
WB 1/1000. Detects a band of approximately 35 kDa (predicted molecular weight: 55 kDa).
  • Application notes
    Is unsuitable for Flow Cyt,ICC/IF,IHC-P or IP.
  • Target

    • Function

      Plays a role in the TP53-regulated cellular response to DNA damage probably by cooperating with TP53 (PubMed:16897187, PubMed:18223688, PubMed:21522185). The N-terminal moiety promotes pyroptosis and exhibits bactericidal activity (PubMed:27281216). The physiological relevance of these observations is unknown.
    • Tissue specificity

      Expressed in cochlea. Low level of expression in heart, brain, placenta, lung, liver, skeletal muscle, kidney and pancreas, with highest expression in placenta.
    • Involvement in disease

      Deafness, autosomal dominant, 5
      Is a tumor suppressor gene with an important role in colorectal cancer (CRC).
    • Sequence similarities

      Belongs to the gasdermin family.
    • Domain

      Intramolecular interactions between N- and C-terminal domains may be important for autoinhibition in the absence of activation signal. The intrinsic pyroptosis-inducing activity is carried by the N-terminal domain.
    • Cellular localization

      Cytoplasm, cytosol. Cell membrane.
