RC TISSUE=Liver; RA Flink I.L., Bailey T., Morkin E.; RL Submitted (AUG-1989) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Inhibitor of serine proteases. The primary target is CC elastase, but also has a moderate affinity for plasmin and thrombin. CC -!- SUBUNIT: Interacts with CELA2A (By similarity). Interacts with ERGIC3 CC and LMAN1/ERGIC53 (By similarity). Interacts with PRSS1/Trypsin (By CC similarity). {ECO:0000250|UniProtKB:P01009}. CC -!- SUBCELLULAR LOCATION: Secreted. CC -!- TISSUE SPECIFICITY: Plasma. {ECO:0000269|PubMed:2302382}. CC -!- DOMAIN: The reactive center loop (RCL) extends out from the body of the CC protein and directs binding to the target protease. The protease CC cleaves the serpin at the reactive site within the RCL, establishing a CC covalent linkage between the carboxyl group of the serpin reactive site CC and the serine hydroxyl of the protease. The resulting inactive serpin- CC protease complex is highly stable (By similarity). {ECO:0000250}. CC -!- SIMILARITY: Belongs to the serpin family. {ECO:0000305}.
