Technical Data
CYPB (Peptidyl-prolyl cis-trans Isomerase B, PPIase B, CYP-S1, Cyclophilin B, Rotamase B, S-cyclophilin, SCYLP, PPIB)
Peptidylprolyl isomerase B, also known as Cyclophilin B and PPIB, is a 216aa containing enzyme with peptidyl-prolyl cis-trans isomerase (PPIase) activity and is associated with the secretory pathways and released in biological fluids. It belongs to the cyclophilin-type PPIase family and PPIase B subfamily with a PPIase cyclophilin-type domain and is usually located in the lumen of endoplasmic reticulum and melanosomes. PPIases accelerate the folding of proteins and are known to catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. This cyclosporine-binding protein can also bind to cells derived from T- and B-lymphocytes, and is inhibited by the immunosuppressive drug cyclosporin A (CsA) and is hence an important element in the study of CsA-mediated immunosuppression. Reports also suggest that PPIB is an important component of the HCV replication machinery, acting as a stimulatory regulator of NS5B and could be a possible target for antiviral therapy.
