Protein Structure
UniProt Annotation
Function Cleaves C-terminal arginine or lysine residues from biologically active peptides such as kinins or anaphylatoxins in the circulation thereby regulating their activities. Down- regulates fibrinolysis by removing C-terminal lysine residues from fibrin that has already been partially degraded by plasmin. {ECO:0000269PubMed:10574983}.
Subcellular Localization Secreted.
Disease Associations
Tissue Specificity Plasma; synthesized in the liver.
