  • Target

    • Function

      PPIases accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides.
    • Involvement in disease

      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.
    • Sequence similarities

      Belongs to the cyclophilin-type PPIase family. PPIase B subfamily.
      Contains 1 PPIase cyclophilin-type domain.
    • Cellular localization

      Endoplasmic reticulum lumen. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
