ID:CBPB2_HUMAN DESCRIPTION: RecName: Full=Carboxypeptidase B2; EC=3.4.17.20; AltName: Full=Carboxypeptidase U; Short=CPU; AltName: Full=Plasma carboxypeptidase B; Short=pCPB; AltName: Full=Thrombin-activable fibrinolysis inhibitor; Short=TAFI; Flags: Precursor; 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. CATALYTIC ACTIVITY: Release of C-terminal Arg and Lys from a polypeptide. COFACTOR: Binds 1 zinc ion per subunit. ENZYME REGULATION: TAFI/CPB2 is unique among carboxypeptidases in that it spontaneously inactivates with a short half-life, a property that is crucial for its role in controlling blood clot lysis. The zymogen is stabilized by interactions with the activation peptide. Release of the activation peptide increases a dynamic flap mobility and in time this leads to conformational changes that disrupt the catalytic site and expose a cryptic thrombin-cleavage site present at Arg-324. SUBCELLULAR LOCATION: Secreted. TISSUE SPECIFICITY: Plasma; synthesized in the liver. PTM: N-glycosylated. N-glycan at Asn-108: Hex5HexNAc4. SIMILARITY: Belongs to the peptidase M14 family.

The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
