FK506-binding protein 4 is a protein that in humans is encoded by the FKBP4 gene.The protein encoded by this gene is a member of the immunophilin protein family which play a role in immunoregulation and basic cellular processes involving protein folding and trafficking. This encoded protein is a cis-trans prolyl isomerase that binds to the immunosuppressants FK506 and rapamycin.
