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

    • Function

      Basement membrane-associated chondroitin sulfate proteoglycan (CSPG). Has prolyl 3-hydroxylase activity catalyzing the post-translational formation of 3-hydroxyproline in -Xaa-Pro-Gly- sequences in collagens, especially types IV and V. May be involved in the secretory pathway of cells. Has growth suppressive activity in fibroblasts.
    • Involvement in disease

      Defects in LEPRE1 are the cause of osteogenesis imperfecta type 8 (OI8) [MIM:610915]. A connective tissue disorder characterized by disproportionate short stature, severe osteoporosis, shortening of the long bones, white sclerae, a round face and a short barrel-shaped chest.
    • Sequence similarities

      Belongs to the leprecan family.
      Contains 1 Fe2OG dioxygenase domain.
      Contains 4 TPR repeats.
    • Post-translational

      O-glycosylated; chondroitin sulfate.
    • Cellular localization

      Endoplasmic reticulum. Secreted > extracellular space > extracellular matrix. Secreted into the extracellular matrix as a chondroitin sulfate proteoglycan.

    • Immunocytochemistry/Immunofluorescence analysis of HeLa (Human epithelial cell line from cervix adenocarcinoma) labeling LEPRE1/P3H1 with Purified ab154799 at 1/500 dilution (5µg/ml). Cells were fixed with 100% methanol. ab150077 Goat anti rabbit IgG(Alexa Fluor® 488) at 1/1000 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI. PBS was used instead of the primary antibody as the negative control.
