Glutaminyl-Peptide Cyclotransferase, also known as QPCT is a member ofthe glutaminyl-peptide cyclotransferase family. QPCT is responsible for thebiosynthesis of pyroglutamyl peptides. Furthermore, QPCT is partial againstacidic and tryptophan residues adjacent to the N-terminal glutaminyl residueand a lack of importance of chain length following the second residue. QPCTcatalyzes N-terminal pyroglutamate formation, also in vitro, it catalyzespyroglutamate formation of N-terminally truncated form of APP amyloid-betapeptides [Glu-3]-beta-amyloid.
QPCT produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 339 amino acids (29-361a.a.) and having a molecular mass of 38.7kDa (Molecular size on SDS-PAGE will appear at approximately 28-40kDa). QPCT is expressed with a 6 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.
| UniProt Protein Function: | QPCT: Responsible for the biosynthesis of pyroglutamyl peptides. Has a bias against acidic and tryptophan residues adjacent to the N-terminal glutaminyl residue and a lack of importance of chain length after the second residue. Also catalyzes N-terminal pyroglutamate formation. In vitro, catalyzes pyroglutamate formation of N-terminally truncated form of APP amyloid-beta peptides [Glu-3]-beta-amyloid. May be involved in the N-terminal pyroglutamate formation of several amyloid-related plaque-forming peptides. Belongs to the glutaminyl-peptide cyclotransferase family. 2 isoforms of the human protein are produced by alternative splicing. |

| NCBI Summary: | This gene encodes human pituitary glutaminyl cyclase, which is responsible for the presence of pyroglutamyl residues in many neuroendocrine peptides. The amino acid sequence of this enzyme is 86% identical to that of bovine glutaminyl cyclase. [provided by RefSeq, Jul 2008] |
