Application Abreviews Notes
  • Application notesELISA: Use at an assay dependent dilution.
    WB: Use at an assay dependent dilution. Detects a band of approximately 200 kDa under reducing conditions. (predicted molecular weight: 195 kDa).

    Not tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • FunctionMetalloproteinase which specifically cleaves IGFBP-4 and IGFBP-5, resulting in release of bound IGF. Cleavage of IGFBP-4 is dramatically enhanced by the presence of IGF, whereas cleavage of IGFBP-5 is slightly inhibited by the presence of IGF.
    • Tissue specificityHigh levels in placenta and pregnancy serum. In placenta, expressed in X cells in septa and anchoring villi, and in syncytiotrophoblasts in the chorionic villi. Lower levels are found in a variety of other tissues including kidney, myometrium, endometrium, ovaries, breast, prostate, bone marrow, colon, fibroblasts and osteoblasts.
    • Sequence similaritiesBelongs to the peptidase M43B family.
      Contains 5 Sushi (CCP/SCR) domains.
    • Developmental stagePresent in serum and placenta during pregnancy; levels increase throughout pregnancy.
    • Post-translational
      There appear to be no free sulfhydryl groups.
    • Cellular localizationSecreted.
