GeneID: 5069 Human PAPPA

Swiss-port # Q13219 Human Pappalysin-1

Gene Symbol PAPPA
Gene Full Name pregnancy-associated plasma protein A, pappalysin 1
Background This gene encodes a secreted metalloproteinase which cleaves insulin-like growth factor binding proteins (IGFBPs). It is thought to be involved in local proliferative processes such as wound healing and bone remodeling. Low plasma level of this protein has been suggested as a biochemical marker for pregnancies with aneuploid fetuses. [provided by RefSeq, Jul 2008]
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. [UniProt]
Calculated MW 181 kDa
PTM There appear to be no free sulfhydryl groups.
