Predicted to enable cyclosporin A binding activity and peptidyl-prolyl cis-trans isomerase activity. Predicted to be involved in protein folding. Predicted to be located in cytoplasm and intracellular membrane-bounded organelle. Expressed in intestine. Human ortholog(s) of this gene implicated in osteogenesis imperfecta type 9. Is an ortholog of human PPIB (peptidylprolyl isomerase B).
