Application Abreviews Notes
WB Use at an assay dependent concentration. Predicted molecular weight: 181 kDa.

  • Function

    Metalloproteinase 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 specificity

    High 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 similarities

    Belongs to the peptidase M43B family.
    Contains 5 Sushi (CCP/SCR) domains.
  • Developmental stage

    Present in serum and placenta during pregnancy; levels increase throughout pregnancy.
  • Post-translational

    There appear to be no free sulfhydryl groups.
  • Cellular localization

Thank you for your inquiry.

ab59086: Five different pappalysin-1 sequences are published thus far; 1628, 1627, 1420, 1232 and 704 amino acids in length. The shorter forms start with the second methionine, 209 residues downstream from the long forms, after the LamGL domain. The 1232 sequence lacks the final Notch/Lin domain, the 720 sequence ends after the catalytic domain. The 1628/7, 1420, 1232 and 720 forms have predicted masses of 181, 157.9, 137.1 and 78.7 kDa as monomers, respectively. ab59086 recognizes the 1627/8 amino acid pappalysin-1, but not the shorter forms.

ab52030: I can confirm that the immunogen for ab52030full length immunogen. This antibody is amouse monoclonal and therefore binds only once per protein molecule. The epitope is located on the PAPP A subunit of the heterotetramer. The epitope has not been mapped further.

I hope this information is helpful and wish you good luck with your experiments.

Thank you for your reply.

Iam sorry to confirm thatwe do not have the requested information.

The immunogen used to raise ab52030 was PAPP-A purified from fluid containing maternal serum aspirated during cesarean section (“cesarean fluid”) using heparin affinity chromatography followed by ionexchange chromatography.

NMRI-BALBc mice were injected subcutaneous with the purified PAPP-A in incomplete Freund’s adjuvant.

The purified PAPP-A was not sequenced.

I hope this information will be nevertheless helpful and wish you good luck with your research.
