products description :
Pappalysins belong to a fifth family of metzincin proteases that consists of ADAMs/ADAMTSs, MMPs, astacins and serrylysins. PAPPA is an important pregnancy protein and increases in plasma by a factor of about 150 during pregnancy as compared to the non-pregnant state. PAPPA is also a major marker of Down syndrome in the first trimester of pregnancy because maternal serum levels of PAPPA are significantly reduced when a fetus affected by Down syndrome is present. PAPPA cleaves Insulin-like Growth FactorBinding Protein4 and 5 (IGFBP4 and 5) at a single site, resulting in the release of bioactive IGF. Compared to PAPPA, PAPPA2 (also called PAPPE), the second member of the family is less characterized. PAPPA2 shares 45% amino acid identity to PAPPA in the mature form, which is synthesized as a preproprotein consisting of multiple domains. The prepro region (residues 1-233) and the C-terminal region (residues 1397-1791) are not included in recombinant human PAPPA2.

ncbi summary :
This gene encodes a member of the pappalysin family of metzincin metalloproteinases. The encoded protein cleaves insulin-like growth factor-binding protein 5 and is thought to be a local regulator of insulin-like growth factor (IGF) bioavailability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2010]
uniprot summary :
Function: Metalloproteinase which specifically cleaves IGFBP-5. Shows limited proteolysis toward IGFBP-3. Ref.1. Catalytic activity: Cleavage of the 143-Ser- -Lys-144 bond in insulin-like growth factor binding protein (IGFBP)-5. Cofactor: Binds 1 zinc ion per subunit . By similarity. Subunit structure: Monomer. Subcellular location: Secreted . By similarity. Tissue specificity: Expressed abundantly in placenta, and non-pregnant mammary gland with low expression in the kidney, fetal brain and pancreas. Ref.1 Ref.2. Sequence similarities: Belongs to the peptidase M43B family.Contains 5 Sushi (CCP/SCR) domains. Sequence caution: The sequence AAL17779.1 differs from that shown. Reason: Erroneous initiation. The sequence AAL17780.1 differs from that shown. Reason: Erroneous initiation. The sequence CAC11134.1 differs from that shown. Reason: Erroneous initiation.
