These three classes of proteins areeasily distinguishable by their selective interactions with immunosuppressivedrugs. Cyclophilins are targets for cyclosporin A (CsA), parvulins bind juglone(5-hydroxy-l.4-naphthoquinone) and FKBP, they are inhibited either by FK560drug or by rapamycin. Despite the lack of structural similarity, all these proteinshave been shown to act as peptidylprolyl cis-trans isomerases. In all cases, binding of the drug inhibits their PPIase activity. Distinct isoforms of cyclophilinshave been localized in the cytoplasm, nucleus, mitochondria, chloroplasts andendoplasmic reticulum.}, type={Text}, title={Structure and Function of Cyclophilins}, URL={http://rcin.org.pl/Content/137917/PDF/POZN271_173026_biotechnologia-2002-no3-nuc.pdf}, keywords={biotechnology}, }
