這個基因編碼一個美其辛金屬蛋白酶papplayin家族成員。編碼的蛋白質分裂胰島素樣生長因子結合蛋白5，被認為是胰島素樣生長因子（IGF）生物利用度的局部調節器。選擇性剪接導致多個轉錄變體。
This gene encodes a member of the pappalysin family of metzincin metalloproteinases. The encoded protein cleaves insulin-like growth factor-binding protein 5 and is thought to be a local regulator of insulin-like growth factor (IGF) bioavailability. Alternative splicing results in multiple transcript variants.
