  • Function

    Deubiquitinating enzyme that regulates the degradation of various proteins. Deubiquitinates and prevents proteasomal degradation of RNF123 which in turn stimulates CDKN1B ubiquitin-dependent degradation thereby playing a role in cell proliferation. Involved in decreased protein synthesis in atrophying skeletal muscle. Modulates transcription of major myofibrillar proteins. Also involved in turnover of endoplasmic-reticulum-associated degradation (ERAD) substrates.
  • Sequence similarities

    Belongs to the peptidase C19 family.
    Contains 2 CS domains.
    Contains 1 MYND-type zinc finger.
  • Post-translational

    Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localization

    Endoplasmic reticulum membrane.

    Lane 3: Jurkat cell lysate (40 µg)
    Lane 4: HeLa cell lysate (40 µg)
    Lanes 1 - 4: Merged signal (red and green). Green - ab189518 observed at 160 kDa. Red - loading control, ab8245, observed at 37 kDa.

    ab189518 was shown to recognize USP19  when USP19  knockout samples were used, along with additional cross-reactive bands. Wild-type and USP19  knockout samples were subjected to SDS-PAGE. Ab189518 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10000 dilution respectively and incubated overnight at 4C. 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.
