Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 146 kDa (predicted molecular weight: 146 kDa).
IP Use at 2-5 µg/mg of lysate.


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