RT   "Inhibitory serpins from wheat grain with reactive centers resembling
RT   glutamine-rich repeats of prolamin storage proteins. Cloning and
RT   characterization of five major molecular forms.";
RL   J. Biol. Chem. 275:33272-33279(2000).
CC   -!- FUNCTION: Inhibits chymotrypsin and cathepsin G in vitro.
CC       {ECO:0000269|PubMed:10874043}.
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}.
