Pappalysins comprise one of the five families of Metzincins (other families include ADAMs/ADAMTSs, MMPs, Astacins, and Serralysins).
Pappalysin-1 (PAPP-A) is an important pregnancy protein and increases in plasma by a factor of about 150 during pregnancy.
Reduced maternal serum PAPP-A is a major marker of Down syndrome in the first trimester of pregnancy.
PAPP-A cleaves IGFBP-4 and -5 (insulin-like growth factor-binding protein-4 and 5) at a single site, resulting in the release of bioactive IGF
Pappalysin-2 (PAPP-A2; also called PAPP-E) shares 45%aa identity with PAPP-A and cleaves IGFBP-2.sialic acid binding Ig-like lectin 6 (Siglec-6), a potential leptin receptor, and pappalysin-2 (PAPP-A2), a protease that cleaves IGF-binding proteins
