General annotation (Comments)
| Function | A proteinase activates the inhibitor by specific proteolysis in the bait region, which, by an unknown mechanism leads to reaction at the cysteinyl-glutamyl internal thiol ester site and to a conformational change, whereby the proteinase is trapped and/or covalently bound to the inhibitor. While in the tetrameric proteinase inhibitors steric inhibition is sufficiently strong, monomeric forms need a covalent linkage between the activated glutamyl residue of the original thiol ester and a terminal amino group of a lysine or another nucleophilic group on the proteinase, for inhibition to be effective. |
| Subunit structure | Monomer. |
| Subcellular location | |
| Tissue specificity | Plasma. |
| Sequence similarities | Belongs to the protease inhibitor I39 (alpha-2-macroglobulin) family. [View classification] |
