Carboxypeptidase B2 (TAFI)

Target (abbrv.) TAFI
Target (full name) Carboxypeptidase B2
Somalogic ID (Sequence ID) SL004015 (3518-54_2)
Entrez Gene Symbol CPB2
UniProt ID Q96IY4
UniProt Comment
  • 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.
Wiki Pathways
  • Complement and Coagulation Cascades
  • Metabolism of Angiotensinogen to Angiotensins

All locus annotations are based on the sentinel SNP (rs3742264) and 62 proxy variant(s) that is/are in linkage disequilibrium r2 ≥ 0.8. Linkage disequilibrium is based on data from the 1000 Genomes Project, phase 3 version 5, European population and was retrieved using SNiPA's Block Annotation feature.
