A functional analysis of the spacer of V(D)J recombination signal sequences.
(PLoS Biol, 2003-10)During lymphocyte development, V(D)J recombination assembles antigen receptor genes from component V, D, and J gene segments. These gene segments are flanked by a recombination signal sequence (RSS), which serves as the ... -
High-throughput isolation and mapping of C. elegans mutants susceptible to pathogen infection.
(PLoS One, 2008-08-06)We present a novel strategy that uses high-throughput methods of isolating and mapping C. elegans mutants susceptible to pathogen infection. We show that C. elegans mutants that exhibit an enhanced pathogen accumulation ... -
Human genetic risk of treatment with antiviral nucleoside analog drugs that induce lethal mutagenesis: The special case of molnupiravir.
(Environmental and molecular mutagenesis, 2022-01)This review considers antiviral nucleoside analog drugs, including ribavirin, favipiravir, and molnupiravir, which induce genome error catastrophe in SARS-CoV or SARS-CoV-2 via lethal mutagenesis as a mode of action. In ... -
Mechanism of local and global Ca2+ sensing by calmodulin in complex with a Ca2+ channel.
(Cell, 2008-06-27)Calmodulin (CaM) in complex with Ca(2+) channels constitutes a prototype for Ca(2+) sensors that are intimately colocalized with Ca(2+) sources. The C-lobe of CaM senses local, large Ca(2+) oscillations due to Ca(2+) influx ... -
Metabolic labeling enables selective photocrosslinking of O-GlcNAc-modified proteins to their binding partners.
(Proceedings of the National Academy of Sciences of the United States of America, 2012-03-12)O-linked β-N-acetylglucosamine (O-GlcNAc) is a reversible posttranslational modification found on hundreds of nuclear and cytoplasmic proteins in higher eukaryotes. Despite its ubiquity and essentiality in mammals, functional ... -
MicroRNA antagonism of the picornaviral life cycle: alternative mechanisms of interference.
(PLoS Pathog, 2010-03-19)In addition to modulating the function and stability of cellular mRNAs, microRNAs can profoundly affect the life cycles of viruses bearing sequence complementary targets, a finding recently exploited to ameliorate toxicities ... -
Modeling deterministic effects in hematopoietic system caused by chronic exposure to ionizing radiation in large human cohorts.
(Health Phys, 2010-09)A new model of the hematopoietic system for humans chronically exposed to ionizing radiation allows for quantitative description of the initial hematopoiesis inhibition and subsequent increase in the risks of late stochastic ... -
Stabilization of Topoisomerase 2 Mutants Initiates the Formation of Duplications in DNA
(2021)Topoisomerase 2 (Top2) is an enzyme that helps maintain genome integrity by resolving topological structures that arise during cellular processes such as replication and transcription. To resolve these structures, a Top2 ... -
Topoisomerase 1 (Top1)-associated Genome Instability in Yeast: Effects of Persistent Cleavage Complexes or Increased Top1 Levels
(2016)Topoisomerase 1 (Top1), a Type IB topoisomerase, functions to relieve transcription- and replication-associated torsional stress in DNA. Top1 cleaves one strand of DNA, covalently associates with the 3’ end of the nick to ...
