一般描述
Prolyl oligopeptidase (PO) is mapped to human chromosome 6q22. It comprises of a N-terminal β-propeller domain and C-terminal α/β hydrolase catalytic domain. PO is highly expressed in the neuronal cytoplasm and its expression increases with age.
Prolyl oligopeptidase is a cytosolic serine peptidase which cleaves peptide bonds at the C′ terminal side of prolines. It is only capable of processing peptides containing no more than 30 amino acids due to the unique β-propeller region that regulates access to the active site.
应用
Prolyl oligopeptidase has been used in a study to assess the mechanism of lithium ion action. It has also been used in a study to investigate its distribution in human tissue and body fluids.
Prolyl oligopeptidase has been used in the prolyl oligopeptidase inhibitory activity assay in lyophilized protein hydrolysate samples and Schistosoma mansoni samples.
生化/生理作用
Prolyl oligopeptidase (PO) regulates physiological processes and is crucial for the generation of active hormone and peptide fragments from their precursors. It shows elevated levels in psychiatric disorders and Alzheimer′s patients. Altered levels of PO is observed in patients with bipolar disorder. High expression of PO may promote metastasis of malignant ovarian and colorectal tumors.
