这个基因编码一个美其辛金属蛋白酶papplayin家族成员。编码的蛋白质分裂胰岛素样生长因子结合蛋白5，被认为是胰岛素样生长因子（IGF）生物利用度的局部调节器。选择性剪接导致多个转录变体。
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.
