    COMBREX (http://combrex.bu.edu) is a project to increase the speed of the functional annotation of new bacterial and archaeal genomes. It consists of a database of functional predictions produced by computational biologists ...
  • Rachlin, John; Ding, Chunming; Cantor, Charles; Kasif, Simon (BioMed Central, 2005-7-25)
    BACKGROUND: Multiplex PCR is a key technology for detecting infectious microorganisms, whole-genome sequencing, forensic analysis, and for enabling flexible yet low-cost genotyping. However, the design of a multiplex PCR ...
  • Anton, Brian P.; Russell, Susan P.; Vertrees, Jason; Kasif, Simon; Raleigh, Elisabeth A.; Limbach, Patrick A.; Roberts, Richard J. (2010-5-14)
    Methylthiotransferases (MTTases) are a closely related family of proteins that perform both radical-S-adenosylmethionine (SAM) mediated sulfur insertion and SAM-dependent methylation to modify nucleic acid or protein targets ...
  • Wu, Chang-Jiun; Kasif, Simon (Oxford University Press, 2005-06-27)
    The advent of microarray technology has revolutionized the search for genes that are differentially expressed across a range of cell types or experimental conditions. Traditional clustering methods, such as hierarchical ...
  • Lee, Soohyun; Kohane, Isaac; Kasif, Simon (BioMed Central, 2005-11-27)
    BACKGROUND: Recent advances in genome sequencing suggest a remarkable conservation in gene content of mammalian organisms. The similarity in gene repertoire present in different organisms has increased interest in studying ...
  • Ku, Manching; Koche, Richard P.; Rheinbay, Esther; Mendenhall, Eric M.; Endoh, Mitsuhiro; Mikkelsen, Tarjei S.; Presser, Aviva; Nusbaum, Chad; Xie, Xiaohui; Chi, Andrew S.; Adli, Mazhar; Kasif, Simon; Ptaszek, Leon M.; Cowan, Chad A.; Lander, Eric S.; Koseki, Haruhiko; Bernstein, Bradley E. (Public Library of Science, 2008-10-31)
    In embryonic stem (ES) cells, bivalent chromatin domains with overlapping repressive (H3 lysine 27 tri-methylation) and activating (H3 lysine 4 tri-methylation) histone modifications mark the promoters of more than 2,000 ...
  • Zheng, Yu; Roberts, Richard J; Kasif, Simon (BioMed Central, 2002-10-10)
    The current speed of sequencing already exceeds the capability of annotation. A new method for functional annotation is proposed using the conservation patterns of gene clusters and has been applied to the genome of ...
  • Jiang, Xiaoyu; Nariai, Naoki; Steffen, Martin; Kasif, Simon; Kolaczyk, Eric D (BioMed Central, 2008-8-22)
    BACKGROUND. In the current climate of high-throughput computational biology, the inference of a protein's function from related measurements, such as protein-protein interaction relations, has become a canonical task. Most ...
  • Faith, Jeremiah J; Hayete, Boris; Thaden, Joshua T; Mogno, Ilaria; Wierzbowski, Jamey; Cottarel, Guillaume; Kasif, Simon; Collins, James J; Gardner, Timothy S (Public Library of Science, 2007-1-9)
    Machine learning approaches offer the potential to systematically identify transcriptional regulatory interactions from a compendium of microarray expression profiles. However, experimental validation of the performance ...
  • Rachlin, John; Ding, Chunming; Cantor, Charles; Kasif, Simon (Oxford University Press, 2005-06-27)
    We have developed a web-enabled system called MuPlex that aids researchers in the design of multiplex PCR assays. Multiplex PCR is a key technology for an endless list of applications, including detecting infectious ...
  • Zheng, Yu; Anton, Brian P; Roberts, Richard J; Kasif, Simon (BioMed Central, 2005-10-3)
    BACKGROUND. Microbial genomes contain an abundance of genes with conserved proximity forming clusters on the chromosome. However, the conservation can be a result of many factors such as vertical inheritance, or functional ...
  • Wu, Chang-Jiun; Cai, Tianxi; Rikova, Klarisa; Merberg, David; Kasif, Simon; Steffen, Martin (Public Library of Science, 2009-11-25)
    BACKGROUND. Aberrant activation of signaling pathways drives many of the fundamental biological processes that accompany tumor initiation and progression. Inappropriate phosphorylation of intermediates in these signaling ...
  • Nariai, Naoki; Kolaczyk, Eric D.; Kasif, Simon (Public Library of Science, 2007-3-28)
    Dramatic improvements in high throughput sequencing technologies have led to a staggering growth in the number of predicted genes. However, a large fraction of these newly discovered genes do not have a functional assignment. ...
  • Lee, Soohyun; Kasif, Simon; Weng, Zhiping; Cantor, Charles R. (Public Library of Science, 2008-12-18)
    BACKGROUND. Single nucleotide polymorphisms (SNPs) have been used extensively in genetics and epidemiology studies. Traditionally, SNPs that did not pass the Hardy-Weinberg equilibrium (HWE) test were excluded from these ...
  • Dotan-Cohen, Dikla; Kasif, Simon; Melkman, Avraham A. (Oxford University Press, 2009-6-3)
    Motivation: There is a growing interest in improving the cluster analysis of expression data by incorporating into it prior knowledge, such as the Gene Ontology (GO) annotations of genes, in order to improve the biological ...
