We have developed a novel way of displaying relative changes of amino acid (AA)- residues at a given sequence position by using heat-maps. This type of representation allows simultaneous estimation of conservation level in a given sequence position in the entire group of functionally-related paralogues (multigene family of proteins). We have also proposed that at least two FKBPs, namely FKBP36, encoded by the Fkbp6 gene and FKBP51, encoded by the Fkbp5 gene, can form dimers bound via a disulfide bridge in the nucleus. This type of dimer may have some crucial function in the regulation of some nuclear complexes at different stages of the cell cycle. Keywords: FKBP; cyclophilin; PPIase; heat-map; immunophilin 1 Introduction About 30 years ago, an exciting adventure began in finding some correlations between pharmacological activities of macrocyclic hydrophobic drugs, namely the cyclic peptide cyclosporine A (CsA), and two macrolides, namely FK506 and rapamycin, which have profound and clinically useful immunosuppressive effects, especially in organ transplantations and in combating some immune disorders.

Courtney, Trevor J. Horst, Chasity P. Hankinson, and Alexander Deiters* Department of Chemistry, University of Pittsburgh, Pittsburgh, PA 15260, United States [email protected] Abstract: Rapamycin-induced dimerization of FKBP and FRB has been utilized as a tool for co-localizing two proteins of interest in numerous applications. Due to the tight binding interaction of rapamycin with FKBP and FRB, the ternary complex formation is essentially irreversible. Since biological processes occur in a highly dynamic fashion with cycles of protein association and dissociation to generate a cellular response, it is useful to have chemical tools that function in a similar manner. We have developed arylazopyrazole-modified rapamycin analogs which undergo a configurational change upon light exposure and we observed enhanced ternary complex formation for the cis-isomer over the trans-isomer for one of the analogs. Introduction: Chemical inducers of dimerization (CIDs) are prominent tools used by chemical biologists to place biological processes under conditional control.1-4 The most commonly utilized CID is rapamycin, a natural product that binds to FK506 binding protein (FKBP) with a 0.2 nM Kd.

Enzyme Activity and Structural Features of Three Single-Domain Phloem Cyclophilins from Brassica Napus
www.nature.com/scientificreports OPEN Enzyme activity and structural features of three single-domain phloem cyclophilins from Brassica Received: 20 September 2018 Accepted: 14 June 2019 napus Published: xx xx xxxx Patrizia Hanhart1, Sven Falke2, Marcel Garbe1, Victoria Rose1, Melanie Thieß1, Christian Betzel2 & Julia Kehr 1 Cyclophilins (CYPs) are a group of ubiquitous prolyl cis/trans isomerases (PPIases). It was shown that plants possess the most diverse CYP families and that these are abundant in the phloem long-distance translocation stream. Since phloem exudate showed PPIase activity, three single-domain CYPs that occur in phloem samples from Brassica napus were characterised on functional and structural levels. It could be shown that they exhibit isomerase activity and that this activity is controlled by a redox regulation mechanism, which has been postulated for divergent CYPs. The structure determination by small-angle X-ray scattering experiments revealed a conserved globular shape. In addition, the high-resolution crystal structure of BnCYP19-1 was resolved and refned to 2.0 Å resolution, and the active sites of related CYPs as well as substrate binding were modelled. The obtained data and results support the hypothesis that single domain phloem CYPs are active phloem PPIases that may function as chaperones. Cyclophilins (CYPs) are ubiquitous proteins involved in a number of fundamental cellular functions in a large number of organisms, such as animals, plants, fungi, bacteria and viruses1. Together with the structurally unre- lated FK506-binding proteins (FKBPs), they belong to the superfamily of immunophilins that have originally been discovered as proteins binding to the immunosuppressant peptide drug cyclosporin A (CsA)2 or FK506/ rapamycin3, respectively.

FKBP Ligands—Where We Are and Where to Go?
REVIEW published: 05 December 2018 doi: 10.3389/fphar.2018.01425 FKBP Ligands—Where We Are and Where to Go? Jürgen M. Kolos, Andreas M. Voll, Michael Bauder and Felix Hausch* Department of Chemistry, Institute of Chemistry and Biochemistry, Darmstadt University of Technology, Darmstadt, Germany In recent years, many members of the FK506-binding protein (FKBP) family were increasingly linked to various diseases. The binding domain of FKBPs differs only in a few amino acid residues, but their biological roles are versatile. High-affinity ligands with selectivity between close homologs are scarce. This review will give an overview of the most prominent ligands developed for FKBPs and highlight a perspective for future developments. More precisely, human FKBPs and correlated diseases will be discussed as well as microbial FKBPs in the context of anti-bacterial and anti-fungal therapeutics. The last section gives insights into high-affinity ligands as chemical tools and dimerizers.

Inhibition of the FKBP Family of Peptidyl Prolyl Isomerases Induces Abortive Translocation and Degradation of the Cellular Prion Protein
Inhibition of the FKBP Family of Peptidyl Prolyl Isomerases Induces Abortive Translocation and Degradation of the Cellular Prion Protein by Maxime Sawicki A thesis submitted in conformity with the requirements for the degree of Master of Science Department of Biochemistry University of Toronto © Copyright by Maxime Sawicki 2015 Inhibition of the FKBP Family of Peptidyl Prolyl Isomerases Induces Abortive Translocation and Degradation of the Cellular Prion Protein Maxime Sawicki Master of Science Department of Biochemistry University of Toronto 2015 Abstract Prion disorders are a class of neurodegenerative diseases that feature a structural change of the prion protein from its cellular form (PrPC) into its scrapie form (PrPSc). As these disorders are currently incurable, there is a crucial need for novel therapeutic agents. Here, the FDA-approved immunosuppressive drug FK506 was shown to cause an attenuation in the endoplasmic reticulum (ER) translocation of PrPC by exacerbating an intrinsic inefficiency of PrP’s ER-targeting signal sequence, effectively causing the proteasomal degradation of PrPC. Furthermore, the depletion of FKBP10 also caused the degradation of PrPC but at a later stage following translocation into the ER. Additionally, novel FK506 analogues with reduced immunosuppressive properties were shown to be as efficacious as FK506 in downregulating PrPC. Finally, both FK506 treatment and FKBP10 depletion were shown to reduce the levels of PrPSc in chronically infected cell models. These findings offer a new insight into the development of treatments against prion disorders. ii Acknowledgments The completion of the present thesis would not have been possible without the help and support of a number of people. First and foremost, I would like to thank my supervisor, Dr David Williams, for his constant guidance and expertise that allowed me to successfully complete my degree, as well as my committee members, Dr John Glover and Dr Gerold Schmitt-Ulms, for their invaluable advice and suggestions over the course of this project.

Carver Received: 24 August 2017; Accepted: 26 September 2017; Published: 29 September 2017 Abstract: Analyses of sequences and structures of the cyclosporine A (CsA)-binding proteins (cyclophilins) and the immunosuppressive macrolide FK506-binding proteins (FKBPs) have revealed that they exhibit peculiar spatial distributions of charges, their overall hydrophobicity indexes vary within a considerable level whereas their points isoelectric (pIs) are contained from 4 to 11. These two families of peptidylprolyl cis/trans isomerases (PPIases) have several distinct functional attributes such as: (1) high affinity binding to some pharmacologically-useful hydrophobic macrocyclic drugs; (2) diversified binding epitopes to proteins that may induce transient manifolds with altered flexibility and functional fitness; and (3) electrostatic interactions between positively charged segments of PPIases and negatively charged intracellular entities that support their spatial integration. These three attributes enhance binding of PPIase/pharmacophore complexes to diverse intracellular entities, some of which perturb signalization pathways causing immunosuppression and other system-altering phenomena in humans. Keywords: PPIase; FKBP; cyclophilin; rapamycin; FK506 1. Introduction About forty years ago, two different types of macrocyclic molecules were isolated and shown to possess immunosuppressive activities, such as the cyclic peptide containing non-standard amino acid residues (AAs) cyclosporine A (CsA) and its homologues [1], and two polyketides having L-pipecolic acid ring, namely immunosuppressive macrolide FK506 [2] and rapamycin [3,4].

Comparative Analysis of FKBP Family Protein: Evaluation, Structure, and Function in Mammals and Drosophila Melanogaster
Ghartey-Kwansah et al. BMC Developmental Biology (2018) 18:7 https://doi.org/10.1186/s12861-018-0167-3 REVIEW Open Access Comparative analysis of FKBP family protein: evaluation, structure, and function in mammals and Drosophila melanogaster George Ghartey-Kwansah1,2†, Zhongguang Li1,2†, Rui Feng1,2†, Liyang Wang1,2, Xin Zhou1,2,3, Frederic Z. Chen4, Meng Meng Xu5, Odell Jones6, Yulian Mu7, Shawn Chen4, Joseph Bryant6, Williams B. Isaacs8, Jianjie Ma3 and Xuehong Xu1,2* Abstract Background: FK506-binding proteins (FKBPs) have become the subject of considerable interest in several fields, leading to the identification of several cellular and molecular pathways in which FKBPs impact prenatal development and pathogenesis of many human diseases. Main body: This analysis revealed differences between how mammalian and Drosophila FKBPs mechanisms function in relation to the immunosuppressant drugs, FK506 and rapamycin. Differences that could be used to design insect-specific pesticides. (1) Molecular phylogenetic analysis of FKBP family proteins revealed that the eight known Drosophila FKBPs share homology with the human FKBP12. This indicates a close evolutionary relationship, and possible origination from a common ancestor. (2) The known FKBPs contain FK domains, that is, a prolyl cis/trans isomerase (PPIase) domain that mediates immune suppression through inhibition of calcineurin. The dFKBP59, CG4735/ Shutdown, CG1847, and CG5482 have a Tetratricopeptide receptor domain at the C-terminus, which regulates transcription and protein transportation. (3) FKBP51 and FKBP52 (dFKBP59), along with Cyclophilin 40 and protein phosphatase 5, function as Hsp90 immunophilin co-chaperones within steroid receptor-Hsp90 heterocomplexes. These immunophilins are potential drug targets in pathways associated with normal physiology and may be used to treat a variety of steroid-based diseases by targeting exocytic/endocytic cycling and vesicular trafficking.
