Harvard University November 2016 Abstract EpiProt is a bioinformatics suite designed to help users determine antigenic regions within proteins for the production of antibodies. It combines seven epitope prediction programs (five from the Immune Epitope Database, ABCPred and BcePred) with protein annotation information giving users a comprehensive view of a protein targeted for antigen design. The user can perform BLAST searches using UniProtJAPI to find similar proteins to perform pairwise and multiple sequence alignments using ClustalW, Clustal Omega, MUSCLE, T-coffee, or MAFFT. The resulting alignment is shown in a display where the user can annotate the alignments with predicted epitope regions, post-translational modifications (from PhophoSitePlus and UniProt), subcellular location (UniProt), protein processing (UniProt), secondary structure (from SIFTS/PDB) and predicted secondary structure (PsiPred and JPred). Built using Java 8, EpiProt uses Java Swing to create the graphical user interface. EpiProt is designed with a model-view- presenter (MVP) architecture pattern requiring an internet connection to run and collect data via Representational State Transfer (RESTful) for viewing.

Midha _______________________________ _______________________________ Committee Member Dean of the Graduate School Dr. Yingcai Xiao Dr. George R. Newkome _______________________________ Date ii ABSTRACT A tremendous increase in genomic data has encouraged biologists to turn to bioinformatics in order to assist in its interpretation and processing. One of the present challenges that need to be overcome in order to understand this data more completely is the development of a reliable method to accurately predict the function of a protein from its genomic information. This study focuses on developing an effective algorithm for protein function prediction. The algorithm is based on proteins that have similar expression patterns. The similarity of the expression data is determined using a novel measure, the slope matrix. The slope matrix introduces a normalized method for the comparison of expression levels throughout a proteome. The algorithm is tested using real microarray gene expression data. Their functions are characterized using gene ontology annotations. The results of the case study indicate the protein function prediction algorithm developed is comparable to the prediction algorithms that are based on the annotations of homologous proteins.

  • Comparative Analysis of Human Chromosome 7Q21 and Mouse
    Downloaded from genome.cshlp.org on October 2, 2021 - Published by Cold Spring Harbor Laboratory Press Letter Comparative analysis of human chromosome 7q21 and mouse proximal chromosome 6 reveals a placental-specific imprinted gene, TFPI2/Tfpi2, which requires EHMT2 and EED for allelic-silencing David Monk,1,6 Alexandre Wagschal,2 Philippe Arnaud,2 Pari-Sima Mu¨ller,3 Layla Parker-Katiraee,4 Déborah Bourc’his,5 Stephen W. Scherer,4 Robert Feil,2 Philip Stanier,1 and Gudrun E. Moore1 1Institute of Child Health, London WC1N 1EH, United Kingdom; 2Institute of Molecular Genetics, CNRS UMR-5535 and University of Montpellier-II, 34293 Montpellier, France; 3Sir William Dunn School of Pathology, University of Oxford, Oxford OX1 3RE, United Kingdom; 4Center for Applied Genomics, The Hospital for Sick Children, Toronto M5G 1L7, Canada; 5Inserm U741, F-75251 Paris Cedex 05, France Genomic imprinting is a developmentally important mechanism that involves both differential DNA methylation and allelic histone modifications. Through detailed comparative characterization, a large imprinted domain mapping to chromosome 7q21 in humans and proximal chromosome 6 in mice was redefined. This domain is organized around a maternally methylated CpG island comprising the promoters of the adjacent PEG10 and SGCE imprinted genes. Examination of Dnmt3l−/+ conceptuses shows that imprinted expression for all genes of the cluster depends upon the germline methylation at this putative “imprinting control region” (ICR). Similarly as for other ICRs, we find its DNA-methylated allele to be associated with trimethylation of lysine 9 on histone H3 (H3K9me3) and trimethylation of lysine 20 on histone H4 (H4K20me3), whereas the transcriptionally active paternal allele is enriched in H3K4me2 and H3K9 acetylation.

Abstract Background: Researchers interested in analysing the expression patterns of functionally related genes usually hope to improve the accuracy of their results beyond the boundaries of currently available experimental data. Gene ontology (GO) data provides a novel way to measure the functional relationship between gene products. Many approaches have been reported for calculating the similarities between two GO terms, known as semantic similarities. However, biologists are more interested in the relationship between gene products than in the scores linking the GO terms.

  • MV 12.5.1 Release Notes
    MacVector 12.5.1 for Mac OS X System Requirements MacVector 12.5 runs on any PowerPC or Intel Macintosh running Mac OS X 10.5 or higher. It is a Universal Binary, meaning that it runs natively on both PowerPC and Intel based Macintosh computers. There are no specific hardware requirements for MacVector – if your machine can run OS X 10.5 or above, it can run MacVector. A complete installation of MacVector 12.5 uses approximately 160 MB of disk space. Installation and License Activation Install MacVector 12.5 by double-clicking on the MacVector 12.5.mpkg installer application. You will be prompted for a system administrator account and password during installation. As with MacVector 12.0, once installation is complete, you must enter a valid serial number and activation code the first time you run MacVector. This information is usually sent by e-mail and is also printed on the inside of the CD sleeve. If you previously installed MacVector 12.0 and have a serial number with a maintenance end date of Oct 1st 2011 or later, MacVector 12.5 will automatically use your existing license and you will not be required to enter the details again. Changes for MacVector 12.5.1 Bug Fixes Several occasional crashes have been fixed. Printing from the multiple sequence alignment editor now no longer prints additional blank pages. A bug leading to corrupted data when copying and pasting items between Restriction Enzyme documents has been fixed. The CDS translations display in the single sequence editor now updates correctly when residues are inserted before CDS features in the editor.
