ターゲット情報

  • 機能Serine protease that shows proteolytic activity against a non-specific substrate beta-casein. Promotes or induces cell death either by direct binding to and inhibition of BIRC proteins (also called inhibitor of apoptosis proteins, IAPs), leading to an increase in caspase activity, or by a BIRC inhibition-independent, caspase-independent and serine protease activity-dependent mechanism. Cleaves THAP5 and promotes its degradation during apoptosis. Isoform 2 seems to be proteolytically inactive.
  • 組織特異性Isoform 1 is ubiquitous. Isoform 2 is expressed predominantly in the kidney, colon and thyroid.
  • 関連疾患Defects in HTRA2 are the cause of Parkinson disease type 13 (PARK13) [MIM:610297]. A complex neurodegenerative disorder characterized by bradykinesia, resting tremor, muscular rigidity and postural instability, as well as by a clinically significant response to treatment with levodopa. The pathology involves the loss of dopaminergic neurons in the substantia nigra and the presence of Lewy bodies (intraneuronal accumulations of aggregated proteins), in surviving neurons in various areas of the brain.
  • 配列類似性Belongs to the peptidase S1B family.
    Contains 1 PDZ (DHR) domain.
  • ドメインThe mature N-terminus is involved in the interaction with XIAP.
    The PDZ domain mediates interaction with MXI2.
  • 翻訳後修飾Autoproteolytically activated.
  • 細胞内局在Mitochondrion intermembrane space. Mitochondrion membrane. Predominantly present in the intermembrane space. Released into the cytosol following apoptotic stimuli, such as UV treatment, and stimulation of mitochondria with caspase-8 truncated BID/tBID.

Anti-HtrA2 / Omi antibody [EPR22] 画像

  • All lanes : Anti-HtrA2 / Omi antibody [EPR22] (ab75982) at 1/5000 dilution

    Lane 1 : Jurkat cell lysate
    Lane 2 : 293T cell lysate
    Lane 3 : HeLa cell lysate

    Lysates/proteins at 10 µg per lane.

    Secondary
    HRP labelled goat anti-rabbit at 1/2000 dilution

    Predicted band size : 49 kDa
    Observed band size : 38 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 43 kDa. We are unsure as to the identity of these extra bands.

    Secondary antibody - goat anti-rabbit HRP (ab6721)

  • Overlay histogram showing HeLa cells stained with ab75982 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab75982, 1/100 dilution) for 30 min at 22°C. The secondary antibody used was goat anti-rabbit Alexa Fluor® 488 (IgG H+L) (ab150077) at 1/2000 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1μg/1x106 cells) used under the same conditions. Unlabelled sample (blue line) was also used as a control. Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.
