    Figure S1. DMD module network. The network is formed by 260 genes from DisGeNET and 1101 interactions from STRING. Red nodes are the five seed candidate genes. Figure S2. DMD module network is more connected than a random module of the same size. It is shown the distribution of the largest connected component of 10.000 random modules of the same size of the DMD module network. The green line (x=260) represents the DMD largest connected component, obtaining a z-score=8.9. Figure S3. Shared genes between BMD and DMD signature. A) A meta-analysis of three microarray datasets (GSE3307, GSE13608 and GSE109178) was performed for the identification of differentially expressed genes (DEGs) in BMD muscle biopsies as compared to normal muscle biopsies. Briefly, the GSE13608 dataset included 6 samples of skeletal muscle biopsy from healthy people and 5 samples from BMD patients. Biopsies were taken from either biceps brachii, triceps brachii or deltoid. The GSE3307 dataset included 17 samples of skeletal muscle biopsy from healthy people and 10 samples from BMD patients. The GSE109178 dataset included 14 samples of controls and 11 samples from BMD patients. For both GSE3307 and GSE10917 datasets, biopsies were taken at the time of diagnosis and from the vastus lateralis. For the meta-analysis of GSE13608, GSE3307 and GSE109178, a random effects model of effect size measure was used to integrate gene expression patterns from the two datasets. Genes with an adjusted p value (FDR) < 0.05 and an │effect size│>2 were identified as DEGs and selected for further analysis. A significant number of DEGs (p<0.001) were in common with the DMD signature genes (blue nodes), as determined by a hypergeometric test assessing the significance of the overlap between the BMD DEGs and the number of DMD signature genes B) MCODE analysis of the overlapping genes between BMD DEGs and DMD signature genes.

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.

  • The Ubiquitination Enzymes of Leishmania Mexicana
    The ubiquitination enzymes of Leishmania mexicana Rebecca Jayne Burge Doctor of Philosophy University of York Biology October 2020 Abstract Post-translational modifications such as ubiquitination are important for orchestrating the cellular transformations that occur as the Leishmania parasite differentiates between its main morphological forms, the promastigote and amastigote. Although 20 deubiquitinating enzymes (DUBs) have been partially characterised in Leishmania mexicana, little is known about the role of E1 ubiquitin-activating (E1), E2 ubiquitin- conjugating (E2) and E3 ubiquitin ligase (E3) enzymes in this parasite. Using bioinformatic methods, 2 E1, 13 E2 and 79 E3 genes were identified in the L. mexicana genome. Subsequently, bar-seq analysis of 23 E1, E2 and HECT/RBR E3 null mutants generated in promastigotes using CRISPR-Cas9 revealed that the E2s UBC1/CDC34, UBC2 and UEV1 and the HECT E3 ligase HECT2 are required for successful promastigote to amastigote differentiation and UBA1b, UBC9, UBC14, HECT7 and HECT11 are required for normal proliferation during mouse infection. Null mutants could not be generated for the E1 UBA1a or the E2s UBC3, UBC7, UBC12 and UBC13, suggesting these genes are essential in promastigotes. X-ray crystal structure analysis of UBC2 and UEV1, orthologues of human UBE2N and UBE2V1/UBE2V2 respectively, revealed a heterodimer with a highly conserved structure and interface. Furthermore, recombinant L. mexicana UBA1a was found to load ubiquitin onto UBC2, allowing UBC2- UEV1 to form K63-linked di-ubiquitin chains in vitro. UBC2 was also shown to cooperate with human E3s RNF8 and BIRC2 in vitro to form non-K63-linked polyubiquitin chains, but association of UBC2 with UEV1 inhibits this ability.

  • (USP7) in Histone H2A Ubiquitination
    Characterization of E2E Ubiquitin-Conjugating Enzymes and Ubiquitin-Specific Protease 7 (USP7) in Histone H2A Ubiquitination Hossein Davarinejad A thesis submitted to the Faculty of Graduate Studies in partial fulfillment of the requirements for the degree of Master of Science Graduate Program in Biology York University Toronto, Ontario December 2017 © Hossein Davarinejad, 2017 Abstract Ubiquitin(Ub)-conjugating E2 enzymes play essential roles in ubiquitination of proteins. The UbE2E sub-family members UbE2E1, UbE2E2, and UbE2E3 have N-terminal extensions to the conserved E2 core which contain Ubiquitin-Specific Protease 7 (USP7) binding sequences (P/A/ExxS). Here, we continued our investigations to established that USP7 can interact with E2Es in vitro and in vivo. Our new data indicated that the N-terminal extensions of E2E2 or E2E3 can directly associate with USP7 TRAF domain. We demonstrated that E2E2 or E2E3 are stabilized by USP7 in cells. We also showed that E2Es interact with Ring1B:BMI1, the core components of the Polycomb Repressive Complex 1 (PRC1) and established E2E1 as an in vivo E2 for monoubiquitination of histone H2A on lysine(K) 119. We demonstrated that E2Es can modulate the levels of H2A monoubiquitination in cells and that USP7 may exert an effect on K119-UbH2A levels through regulating E2Es. ii Dedications For my dearest, and departed grandmother. Your memories, love, and grace are eternal. I also dedicate this to Agnieszka, GhoorGhoor, and Charlie for their invaluable support. And for science; may our collective and ever developing understanding of the universe and life lead us to make the world a better and a more peaceful place, for all life is precious.

Abstract Although the cellular and molecular responses to exposure to relatively high temperatures (acute thermal stress or heat shock) have been studied previously, only sparse empirical evidence of how it affects cold-water species is available. As climate change becomes more pronounced in areas such as the Western Antarctic Peninsula, it has become crucial to understand the capacity of these species to respond to thermal stress.

  • Structural and Functional Analyses of the Interaction Between the Usp7-Ntd and the E2-Conjugating Enzymes, Ube2e2 and Ube2e3
    STRUCTURAL AND FUNCTIONAL ANALYSES OF THE INTERACTION BETWEEN THE USP7-NTD AND THE E2-CONJUGATING ENZYMES, UBE2E2 AND UBE2E3 LEILA ASHUROV A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE GRADUATE PROGRAM IN BIOLOGY YORK UNIVERSITY TORONTO, ONTARIO AUGUST 2014 © LEILA ASHUROV, 2014 ABSTRACT Ubiquitin-specific protease 7 (USP7) is a deubiquitinating enzyme that regulates the turnover of proteins in a cell. To date several interacting partners that are involved in various cellular processes have been identified for USP7. Many of the interacting partners of USP7 contain a P/AxxS motif. We have identified two E2 ubiquitin- conjugating enzymes, UbE2E2 and UbE2E3, which contain the P/AxxS motif. Using a co-immunoprecipitation assay we have shown that these E2 proteins interact with USP7 through their P/AxxS motif. Co-crystal structures of the N-terminal domain of USP7 (USP7-NTD) and the E2 peptides reveal that the interactions are formed between USP7- NTD residues 164DWGF167 and the E2 P/AxxS motifs. It has also been established that USP7 may be involved in regulating the cellular levels of UbE2E2. Overall, our findings suggest USP7, a de-ubiquitinating enzyme, is a regulator of ubiquitin-conjugating enzymes, which are involved in the ubiquitination cascade. ii ACKNOWLEDGEMENTS I would like to give my utmost gratitude to my Supervisor Dr. Vivian Saridakis. Thank you for taking me into your lab and providing me with this tremendous opportunity. Your constant support and guidance has allowed me to achieve my goals and complete this project.
