Application Abreviews Notes
WB 1/10000 - 1/20000. Detects a band of approximately 51 kDa (predicted molecular weight: 51 kDa).
IP 1/20.

For unpurified use at 1/50. 

  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function
      Blocks interferon-dependent interphase and stimulates DNA synthesis in cells. Involved in the translational regulation of the human papillomavirus type 16 E7 mRNA (HPV16 E7).
    • Tissue specificity
      Expressed in cultured epidermal, bronchial and mesothelial cells but absent in colon, ectocervix and liver. Observed throughout the glandular cells in the junction between stomach and esophagus but is absent in the esophagus.
    • Sequence similarities
      Belongs to the intermediate filament family.
    • Post-translational
      Arg-20 is dimethylated, probably to asymmetric dimethylarginine.
