Compression of Large Sets of Sequence Data Reveals Fine Diversification of Functional Profiles in Multigene Families of Proteins
Technical note Compression of Large Sets of Sequence Data Reveals Fine Diversification of Functional Profiles in Multigene Families of Proteins: A Study for Peptidyl-Prolyl cis/trans Isomerases (PPIase) Andrzej Galat Retired from: Service d’Ingénierie Moléculaire des Protéines (SIMOPRO), CEA-Université Paris-Saclay, France; [email protected]; Tel.: +33-0164465072 Received: 21 December 2018; Accepted: 21 January 2019; Published: 11 February 2019 Abstract: In this technical note, we describe analyses of more than 15,000 sequences of FK506- binding proteins (FKBP) and cyclophilins, also known as peptidyl-prolyl cis/trans isomerases (PPIases). 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. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -
Role of Phospholipases in Adrenal Steroidogenesis

In some Key Words cases, their activity results in remodeling of lipids and/or allows the synthesis of other f adrenal cortex lipids. In other cases, however, and of interest to the topic of adrenal steroidogenesis, f angiotensin phospholipases produce second messengers that modify the function of a cell. In this f intracellular signaling review, the enzymatic reactions, products, and effectors of three phospholipases, f phospholipids phospholipase C, phospholipase D, and phospholipase A2, are discussed. Although f signal transduction much data have been obtained concerning the role of phospholipases C and D in regulating adrenal steroid hormone production, there are still many gaps in our knowledge. Furthermore, little is known about the involvement of phospholipase A2, Endocrinology perhaps, in part, because this enzyme comprises a large family of related enzymes of that are differentially regulated and with different functions. This review presents the evidence supporting the role of each of these phospholipases in steroidogenesis in the Journal Journal of Endocrinology adrenal cortex.

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. -

(IDivision of Toxicological Science, Johns Hopkins University School of Hygiene and Public Health Abstract-The immunosuppressant drugs cyclosporin A and FK506 bind to small, predominantly soluble proteins cyclophilin and FK506 binding protein, respectively, to mediate their pharmacological actions. The immunosuppressant actions of these drugs occur through binding of cyclophilin-cyclosporinA and FK506 binding protein-FK506 complexes to the calcium-calmodulin-dependent protein phosphatase, calcineurin, inhibiting phosphatase activity, Utilizing immunohistcchemistry, in situ hybridization and autoradiography, we have localized protein and messenger RNA for FKS06 binding protein, cyclophilin and calcineurin. All three proteins and/or messages exhibit a heterogenous distribution through the brain and spinal cord, with the majority of the localizations being neuronal.
