This entry represents the C-terminal part of the SD scarf domain human Pappalysin-1 (PAPPA) [7] and similar predominantly animal sequences. PAPPA is a metalloproteinase that specifically cleaves IGFBP-4 and IGFBP-5, resulting in release of bound IGF [3-5]. This region shows two antiparallel beta-sheets [7].	Domain
