Application Abreviews Notes
WB 1/500 - 1/3000. Predicted molecular weight: Isoform 2, 133 ; Isoform 1, 146 kDa.
IHC-P 1/100 - 1/500.


  • Function

    Binds to the ubiquitin moieties of preformed conjugates and catalyzes ubiquitin chain assembly in conjunction with E1, E2, and E3.
  • Tissue specificity

    Highest expression in ovary, testis, heart and skeletal muscle. Expression is low in colon, thymus and peripheral blood leukocytes. Almost undetectable in lung and spleen.
  • Sequence similarities

    Belongs to the ubiquitin conjugation factor E4 family.
    Contains 1 U-box domain.
  • Post-translational

    Proteolytically cleaved by caspases during apoptosis. Cleaved efficiently at Asp-123 by caspase-6 and granzyme B. Cleaved with approximately 10-fold less efficiency at Asp-109 by caspase-3 and caspase-7.
