caution:Could be the product of a pseudogene.,domain:The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.,function:Could be a serine protease inhibitor.,similarity:Belongs to the serpin family.,
Endoplasmic reticulum .
