Application Abreviews Notes
IHC-P Use a concentration of 10 - 15 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • 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.
