InnateDB Gene IDBG-18320 (SERPINA4)
Protein Structure
UniProt Annotation
Function Inhibits human amidolytic and kininogenase activities of tissue kallikrein. Inhibition is achieved by formation of an equimolar, heat- and SDS-stable complex between the inhibitor and the enzyme, and generation of a small C-terminal fragment of the inhibitor due to cleavage at the reactive site by tissue kallikrein. {ECO:0000269PubMed:8227002}.
Subcellular Localization Secreted.
Disease Associations
Tissue Specificity Expressed by the liver and secreted in plasma.
