Disease
PPIB_HUMAN Defects in PPIB are the cause of osteogenesis imperfecta type 9 (OI9) [MIM:259440. OI9 is a connective tissue disorder characterized by bone fragility, low bone mass and bowing of limbs due to multiple fractures. Short limb dwarfism and blue sclerae are observed in some but not all patients.[1] [2]
Function
PPIB_HUMAN PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
