  • Function

    The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides. Replacement of PSMB6 by PSMB9 increases the capacity of the immunoproteasome to cleave model peptides after hydrophobic and basic residues.
  • Sequence similarities

    Belongs to the peptidase T1B family.
  • Developmental stage

    Highly expressed in immature dendritic cells (at protein level).
  • Post-translational

    Autocleaved. The resulting N-terminal Thr residue of the mature subunit is responsible for the nucleophile proteolytic activity.
  • Cellular localization

    Cytoplasm. Nucleus.

  • Lane 1: Wild-type HAP1 cell lysate (20 µg)
    Lane 2: Proteasome 20S LMP2 knockout HAP1 cell lysate (20 µg)
    Lanes 1 - 2: Merged signal (red and green). Green - ab184172 observed at 22 and 24 kDa. Red - loading control, ab8245, observed at 37 kDa.
    ab184172 was shown to specifically react with Proteasome 20S LMP2 when Proteasome 20S LMP2 knockout samples were used. Wild-type and Proteasome 20S LMP2 knockout samples were subjected to SDS-PAGE. ab184172 and ab8245 (loading control to GAPDH) were both diluted 1/10 000 and incubated overnight at 4°C. 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.

  • Immunofluorescent analysis of 4% paraformaldehyde fixed HL-60 (Human promyelocytic leukemia cell line) cells labeling Proteasome 20S LMP2 using ab184172 at 1/100 dilution (red). A Goat anti rabbit IgG (Alexa Fluor®555) at 1/200 dilution was used as secondary antibody. Counterstain: DAPI (blue).

  • All lanes : Anti-EXTL1 antibody - C-terminal (ab174172) at 1/100000 dilution

    Lane 1 : Ramos cell lysate
    Lane 2 : A431 cell lysate
    Lane 3 : Raji cell lysate

    Lysates/proteins at 20 µg per lane.

    All lanes : Goat Anti-Rabbit IgG, (H+L), Peroxidase conjugated at 1/1000 dilution

    Predicted band size: 23 kDa

  • Immunoprecipitation analysis of Raji cells labeling Proteasome 20S LMP2 using ab184172 at 1/50 dilution (Lane 1). A Anti-Rabbit IgG (HRP), specific to the non-reduced form of IgG at 1/1500 was used as secondary antibody. Lane 2: PBS instead of Raji lysates. Blocking/dilution buffer and concentration: 5% NFDM/TBST.
