| Type | domain | Description | 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. Variability within the reactive center loop (RCL) sequences of Serpina1-related genes may determine target protease specificity (By similarity). |
