NCIt definition : Pappalysin-1 (1627 aa, 181 kDa) is encoded by the human PAPPA gene. This protein
is involved in the modulation of proteolysis.;
NCIt note : Pappalysin-1 specifically cleaves IGFBP-4 between 143-Ser and Lys-144 and IGFBP-5
between 135-Met and Lys-136. (UniProt); Low plasma levels of pappalysin-1 during pregnancy may be a biomarker of an aneuploid
fetus.;
