The FKBPs, or FK506 binding proteins, constitute a family of proteins that have prolyl isomerase activity and are related to the cyclophilins in function, though not in amino acid sequence. FKBPs have been identified in many eukaryotes, ranging from yeast to humans, and function as protein folding chaperones for proteins containing proline residues. Along with cyclophilin, FKBPs belong to the WebMar 15, 2011 · Additional methods use (i) rapamycin (Rap), which binds FKBP (FK506 binding protein) and Frb [FKBP-Rap binding domain of mammalian target of Rap (mTOR)], or (ii) FK506, which binds FKBP and calcineurin, or cyclosporin A, to regulate cellular processes in response to the addition of either Rap or FK506, respectively.
