妊娠相關血漿蛋白A（英語：pregnancy-associated plasma protein A，或Pappalysin-1，縮寫PAPP-A）是一種由人類基因 PAPPA 編碼的蛋白質，PAPP-A是一種分泌蛋白酶，其主要基質是胰島素樣生長因子結合蛋白。PAPP-A也用於唐氏綜合症的篩查試驗。^[5]^[6]

功能

此基因編碼一種分泌的金屬蛋白酶，主要用於切割胰島素樣生長因子的結合蛋白（IGFBPs）。PAPP-A的蛋白水解活性在與膠原蛋白結合後被活化，參與許多局部增生過程，比如傷口癒合和骨重塑。血漿中出現低水平的此蛋白被認為是妊娠中出現非整倍體胎兒（胎兒擁有不正常的染色體數）的生化標誌物^[6]，比如在唐氏綜合症的產前診斷中，低水平的PAPP-A是一個重要標誌^[5]。低水平的PAPP-A也可表明胎盤存在問題，並導致不良併發症如宮內生長受限、妊娠毒血症、胎盤早期剝離、早產乃至死產。

相互作用

妊娠相關血漿蛋白A已知可與主要鹼性蛋白發生蛋白質交互作用。^[7]^[8]^[9]
