TPP2 Antibody / Tripeptidyl-peptidase 2

Tripeptidyl-peptidase 2 is an enzyme that in humans is encoded by the TPP2 gene. This gene encodes a mammalian peptidase that, at neutral pH, removes tripeptides from the N terminus of longer peptides. The protein has a specialized function that is essential for some MHC class I antigen presentation. The protein is a high molecular mass serine exopeptidase; the amino acid sequence surrounding the serine residue at the active site is similar to the peptidases of the subtilisin class rather than the trypsin class.
