Application Abreviews Notes
IHC-P Use at an assay dependent concentration. Perform heat mediated antigen retrieval with Tris/EDTA buffer pH 9.0 before commencing with IHC staining protocol.
IP Use at an assay dependent concentration.
WB Use at an assay dependent concentration. Detects a band of approximately 93 kDa (predicted molecular weight: 93 kDa).


  • Function

    Binds to heparin. Induces cell attachment and spreading and plays a role in cell adhesion. May play a role in extracellular matrix mineralization.
  • Tissue specificity

    Widely expressed with highest levels in aorta, stomach, lower gastrointestinal tract, placenta, uterus and breast. Up-regulated in epithelial ovarian tumors. Not expressed in normal ovaries. Also highly expressed at the tumor periphery of lung carcinoma tissue but not within the tumor. Overexpressed in breast cancers.
  • Sequence similarities

    Contains 1 EMI domain.
    Contains 4 FAS1 domains.
  • Post-translational

    Gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium.
  • Cellular localization

    Secreted > extracellular space > extracellular matrix.
