功能: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.

- TAFIa elicited anti-angiogenic responses by endothelial cells: decreased endothelial cell proliferation, cell invasion, cell migration, tube formation, and collagen degradation. It decreased tube formation and proteolysis in endothelial cell culture grown alone and in co-culture with breast cancer cell lines.
