In turn, drug design process, especially the fragment-based approaches, could benefit from the knowledge. Retrospective virtual screening campaigns by employing AutoDock Vina followed by protein-ligand interaction finger- printing (PLIF) identification by using recently published PyPLIF HIPPOS were the main techniques used here. The ligands and decoys datasets from the enhanced version of the database of useful de- coys (DUDE) targeting human G protein-coupled receptors (GPCRs) were employed in this research since the mutation data are available and could be used to retrospectively verify the prediction. The results show that the method presented in this article could pinpoint some retrospectively verified molecular determinants. The method is therefore suggested to be employed as a routine in drug Citation: Istyastono, E.P.; Yuniarti, design and discovery. N.; Prasasty, V.D.; Mungkasi, S.

Development of Novel Strategies for Template-Based Protein Structure Prediction
Imperial College London Department of Life Sciences PhD Thesis Development of novel strategies for template-based protein structure prediction Stefans Mezulis supervised by Prof. Michael Sternberg Prof. William Knottenbelt September 2016 Abstract The most successful methods for predicting the structure of a protein from its sequence rely on identifying homologous sequences with a known struc- ture and building a model from these structures. A key component of these homology modelling pipelines is a model combination method, responsible for combining homologous structures into a coherent whole. Presented in this thesis is poing2, a model combination method using physics-, knowledge- and template-based constraints to assemble proteins us- ing information from known structures. By combining intrinsic bond length, angle and torsional constraints with long- and short-range information ex- tracted from template structures, poing2 assembles simplified protein models using molecular dynamics algorithms. Compared to the widely-used model combination tool MODELLER, poing2 is able to assemble models of ap- proximately equal quality. When supplied only with poor quality templates or templates that do not cover the majority of the query sequence, poing2 significantly outperforms MODELLER. Additionally presented in this work is PhyreStorm, a tool for quickly and accurately aligning the three-dimensional structure of a query protein with the Protein Data Bank (PDB). The PhyreStorm web server provides comprehensive, current and rapid structural comparisons to the protein data bank, providing researchers with another tool from which a range of biological insights may be drawn. By partitioning the PDB into clusters of similar structures and performing an initial alignment to the representatives of each cluster, PhyreStorm is able to quickly determine which structures should be excluded from the alignment. -

Key words: SVA, trans-mobilisation, behaviour, brain, evolution, psychiatric disorders 1 Abstract The hominid-specific non-LTR retrotransposon termed SINE–VNTR–Alu (SVA) is the youngest of the transposable elements in the human genome. The propagation of the most ancient SVA type A took place about 13.5 Myrs ago, and the youngest SVA types appeared in the human genome after the chimpanzee divergence. Functional enrichment analysis of genes associated with SVA insertions demonstrated their strong link to multiple ontological categories attributed to brain function and the disorders. SVA types that expanded their presence in the human genome at different stages of hominoid life history were also associated with progressively evolving behavioural features that indicated a potential impact of SVA propagation on a cognitive ability of a modern human. -

Publication history: Received on 09 April 2020; revised on 13 April 2020; accepted on 15 April 2020 Article DOI: https://doi.org/10.30574/gscbps.2020.11.1.0099 Abstract Coronavirus infection has turned into pandemic despite of efforts of efforts of countries like America, Italy, China, France etc. Currently India is also outraged by the virulent effect of coronavirus. Although World Health Organisation initially claimed to have all controls over the virus, till date infection has coasted several lives worldwide. Currently we do not have enough time for carrying out traditional approaches of drug discovery. Computer aided drug designing approaches are the best solution. The present study is completely dedicated to in silico approaches like virtual screening, molecular docking and molecular property calculation. The library of 15 bioactive molecules was built and virtual screening was carried towards the crystalline structure of human coronavirus (6nzk) which was downloaded from protein database. Pyrx virtual screening tool was used and results revealed that F14 showed best binding affinity. The best screened molecule was further allowed to dock with the target using Autodock vina software. -

Tyrosine-protein kinase FGR is a protein, member of the Src family kinases (SFks), nonreceptor tyrosine kinases involved in regulating various signaling pathways that promote cell proliferation and migration. FGR protein is also called Gardner-Rasheed Feline Sarcoma viral (v-fgr) oncogene homolog. FGR, FGR protein has an aberrant expression upregulated and activated by the tumor necrosis factor activation (TNF), enhancing the activity of FGR by phosphorylation and activation, causing ovarian cancer. In the present study, 3D structure of FGR protein is built by using comparative homology modeling techniques using MODELLER9.9 program. Energy minimization of protein is done by NAMD-VMD software. The quality of the protein is evaluated with ProSA, Verify 3D and Ramchandran Plot validated tools. The active site of protein is generated using SiteMap and literature Studies. In the present study of research, FGR protein was subjected to virtual screening with TOSLab ligand molecules database in the Schrodinger suite, to result in 12 lead molecules prioritized based on docking score, binding free energy and ADME properties. -

Characterizing Genomic Duplication in Autism Spectrum Disorder by Edward James Higginbotham a Thesis Submitted in Conformity
Characterizing Genomic Duplication in Autism Spectrum Disorder by Edward James Higginbotham A thesis submitted in conformity with the requirements for the degree of Master of Science Graduate Department of Molecular Genetics University of Toronto © Copyright by Edward James Higginbotham 2020 i Abstract Characterizing Genomic Duplication in Autism Spectrum Disorder Edward James Higginbotham Master of Science Graduate Department of Molecular Genetics University of Toronto 2020 Duplication, the gain of additional copies of genomic material relative to its ancestral diploid state is yet to achieve full appreciation for its role in human traits and disease. Challenges include accurately genotyping, annotating, and characterizing the properties of duplications, and resolving duplication mechanisms. Whole genome sequencing, in principle, should enable accurate detection of duplications in a single experiment. This thesis makes use of the technology to catalogue disease relevant duplications in the genomes of 2,739 individuals with Autism Spectrum Disorder (ASD) who enrolled in the Autism Speaks MSSNG Project. Fine-mapping the breakpoint junctions of 259 ASD-relevant duplications identified 34 (13.1%) variants with complex genomic structures as well as tandem (193/259, 74.5%) and NAHR- mediated (6/259, 2.3%) duplications. As whole genome sequencing-based studies expand in scale and reach, a continued focus on generating high-quality, standardized duplication data will be prerequisite to addressing their associated biological mechanisms. ii Acknowledgements I thank Dr. Stephen Scherer for his leadership par excellence, his generosity, and for giving me a chance. I am grateful for his investment and the opportunities afforded me, from which I have learned and benefited. I would next thank Drs. -
WHITE PAPER in SUPPORT of RESEARCH on GENE REGULATORY NETWORKS (Draft Date: 9/18/2016)
WHITE PAPER IN SUPPORT OF RESEARCH ON GENE REGULATORY NETWORKS (draft date: 9/18/2016) TABLE OF CONTENTS 1. Executive Summary 2. Introduction: Goals of this GRN White Paper 3. The GRN paradigm 4. Impact of GRN science on various research fields 5. What is needed for GRN science 6. Mechanisms to achieve goals 7. Conclusion statement 8. Appendices 1 1. EXECUTIVE SUMMARY Gene regulatory networks (GRNs) constitute the genomic control systems for a broad range of biological processes, including the definition of spatial organization during development, morphogenesis, the differentiation of cell types, and the physiological response to internal and external changes in animals, plants, and prokaryotes. In recent years, the successful solution of several GRNs demonstrated the feasibility of addressing experimentally and computationally the causal control system of a variety of biological processes, opening the gate to a new area of biological sciences. However, despite these important advancements, only a few biological processes have so far been addressed at the GRN level. With this White Paper, we aim to bridge this current gap by illuminating the exciting possibilities of this novel research field, and by providing information and guidelines to facilitate the experimental and computational application of the GRN framework to a variety of biological contexts. The focus of GRN studies is to understand biological function as a consequence of genomic programs. GRN science addresses the mechanism and causality of development and other biological processes in terms of genomic information processing. Even in the simplest of animals, a layer of intricate regulatory commands is needed for development of the body plan and to control spatial and temporal gene expression. -
Weighted Burden Analysis of Exome-Sequenced Case-Control Sample Implicates Synaptic Genes in Schizophrenia Aetiology
Behavior Genetics (2018) 48:198–208 https://doi.org/10.1007/s10519-018-9893-3 ORIGINAL RESEARCH Weighted Burden Analysis of Exome-Sequenced Case-Control Sample Implicates Synaptic Genes in Schizophrenia Aetiology David Curtis1,2 · Leda Coelewij1 · Shou‑Hwa Liu1 · Jack Humphrey1,3 · Richard Mott1 Received: 22 November 2017 / Accepted: 13 March 2018 / Published online: 21 March 2018 © The Author(s) 2018 Abstract A previous study of exome-sequenced schizophrenia cases and controls reported an excess of singleton, gene-disruptive vari- ants among cases, concentrated in particular gene sets. The dataset included a number of subjects with a substantial Finnish contribution to ancestry. We have reanalysed the same dataset after removal of these subjects and we have also included non- singleton variants of all types using a weighted burden test which assigns higher weights to variants predicted to have a greater effect on protein function. We investigated the same 31 gene sets as previously and also 1454 GO gene sets. The reduced dataset consisted of 4225 cases and 5834 controls. No individual variants or genes were significantly enriched in cases but 13 out of the 31 gene sets were significant after Bonferroni correction and the “FMRP targets” set produced a signed log p value (SLP) of 7.1. The gene within this set with the highest SLP, equal to 3.4, was FYN, which codes for a tyrosine kinase which phosphorylates glutamate metabotropic receptors and ionotropic NMDA receptors, thus modulating their trafficking, subcellular distribution and function. In the most recent GWAS of schizophrenia it was identified as a “prioritized candidate gene”.
