  • Function

    Zinc metalloprotease that specifically cleaves 'Lys-63'-linked polyubiquitin chains. Does not cleave 'Lys-48'-linked polyubiquitin chains (By similarity). Functions at the endosome and is able to oppose the ubiquitin-dependent sorting of receptors to lysosomes. Plays a role in signal transduction for cell growth and MYC induction mediated by IL-2 and GM-CSF. Potentiates BMP (bone morphogenetic protein) signaling by antagonizing the inhibitory action of SMAD6 and SMAD7.
  • Tissue specificity

    Ubiquitously expressed.
  • Sequence similarities

    Belongs to the peptidase M67C family.
    Contains 1 MPN (JAB/Mov34) domain.
  • Domain

    The JAMM motif is essential for the protease activity.
  • Post-translational

    Phosphorylated after BMP type I receptor activation.
    Ubiquitinated by SMURF2 in the presence of RNF11.
  • Cellular localization

    Nucleus. Membrane. Cytoplasm. Early endosome.

  • Lane 1: Wild-type HAP1 whole cell lysate (20 µg)
    Lane 2: AMSH knockout  HAP1 whole cell lysate (20 µg)
    Lane 3: Jurkat whole cell lysate (20 µg)
    Lane 4: HeLa whole cell lysate (20 µg)

    Lanes 1 - 4: Merged signal (red and green). Green - ab108301 observed at 48 kDa. Red - loading control, ab9484, observed at 37 kDa.

    ab108301 was shown to specifically react with AMSH in wild-type HAP1 cells along with additional cross-reactive bands. No band was observed when AMSH knockout samples were examined. Wild-type and AMSH knockout samples were subjected to SDS-PAGE.  Ab108301 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
