  • Application notes
    Is unsuitable for IHC-P or IP.
  • Target

    • Function

      Likely to represent an endoprotease activity within the constitutive secretory pathway, with unique restricted distribution in both neuroendocrine and non-neuroendocrine tissues and capable of cleavage at the RX(K/R)R consensus motif.
    • Tissue specificity

      Each PACE4 isoform exhibits a unique restricted distribution. Isoform PACE4A-I is expressed in heart, brain, placenta, lung, skeletal muscle, kidney, pancreas, but at comparatively higher levels in the liver. Isoform PACE4A-II is at least expressed in placenta. Isoform PACE4B was only found in the embryonic kidney cell line from which it was isolated. Isoform PACE4C and isoform PACE4D are expressed in placenta. Isoform PACE4E-I is expressed in cerebellum, placenta and pituitary. Isoform PACE4E-II is at least present in cerebellum.
    • Sequence similarities

      Belongs to the peptidase S8 family.
      Contains 1 homo B/P domain.
      Contains 1 PLAC domain.
    • Domain

      The propeptide domain acts as an intramolecular chaperone assisting the folding of the zymogen within the endoplasmic reticulum. Isoform PACE4D lacks the propeptide domain.
    • Cellular localization

      Secreted; Endomembrane system. Retained intracellularly probably through a hydrophobic cluster in their C-terminus and Endoplasmic reticulum. Not secreted, remains probably in zymogen form in endoplasmic reticulum.

    • ab151562 staining HeLa cells by ICC/IF. The cells were fixed with methanol. The cells were then stained with ab151562 at 1/200 in PBS for 1h at 22°C. An Alexa Fluro 488 goat anti-rabbit polyclonal antibody at 1/200 was used as the secondary antibody. ab151562 produces a focal staining pattern that is enriched within the cytoplasm.
