The protein encoded by FKBP10 gene belongs to the FKBP-type peptidyl-prolyl cis/trans isomerase (PPIase) family. This protein is found in the endoplasmic reticulum and acts as a molecular chaperone. The FKBP10 protein is important for the correct processing of collagen and elastin. Mutations that cause osteogenesis imperfecta type XI and Bruck syndrome 1 lead to the production of little to no FKBP10 protein, thereby, severely impairing collagen cross-linking.
