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]
GeneCards Summary for QPCT Gene
QPCT (Glutaminyl-Peptide Cyclotransferase) is a Protein Coding gene. GO annotations related to this gene include peptidase activity and glutaminyl-peptide cyclotransferase activity. An important paralog of this gene is QPCTL.
UniProtKB/Swiss-Prot for QPCT Gene
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.
