1 Gesteland, Raymond F.; Krapcho, Karen J.; Talbot, Phil; Thulin, CraigCrystallization of the MS2 translational repressor alone and complexed to bromouridineThe coat protein from the MS2 bacteriophage plays a dual role by encapsidating viral RNA and also by binding RNA as a translational repressor. In order to study the isolated dimer in a conformation not influenced by capsid interactions, a mutant molecule was crystallized that is defective in capsid ...Crystallization; RNA Bacteriophage; RNA Hairpin; Translational Repressor1995
2 Horch, Kenneth W.; Christensen, Douglas A.Accelerated 4-year bachelors/masters degree program in biomedical engineeringIn response to the need for providing advanced engineering education in a shorter time period than is currently possible by traditional curricula, we have created an Accelerated Dual Degree program in biomedical engineering. The purpose of this pilot program is to attract the brightest students, g...Accelerated dual-degree program2002

4 Gesteland, Raymond F.; Atkins, John F.; Tuohy, Therese M.Uninterrupted translation through putative 12-nucleotide coding gap in sequence of carA: business as usualPrevious work of others reported an untranslated stretch of 12 nucleotides in the 5' coding sequence of carA from Pseudomonas aeruginosa. However, N-terminal protein sequencing of carA-lacZ translational fusions shows that these 12 nucleotides are normally translated in a continuous triplet manner, ...Base Sequence; Protein Biosynthesis; Sequence Deletion1994
5 Gesteland, Raymond F.; Atkins, John F.; Weiss, Robert B.Slippery runs, shifty stops, backward steps and forward hops: -2, -1, +1, +2, +5 and +6 Ribosomal frameshiftingFrameshift mutations frequently express residual levels of gene activity; that is, they are often leaky. This leakiness can be used as a tool to define the functional components that affect the reading frame during gene expression. Recent technological advances in the capability to efficiently bu...Molecular Sequence Data; Mutation; RNA, Transfer; Frameshifting1987
6 Gesteland, Raymond F.; Atkins, John F.Evolutionary specialization of recoding: frameshifting in the expression of S. cerevisiae antizyme mRNA is via an atypical antizyme shift site but is still +1An autoregulatory translational shift to the +1 frame is required for the expression of ornithine decarboxylase antizyme from fungi to mammals. In most eukaryotes, including all vertebrates and a majority of the studied fungi/yeast, the site on antizyme mRNA where the shift occurs is UCC-UGA. The me...Antizyme; ODC; Polyamines; Frameshifting2006
7 Christensen, Douglas A.; Horch, Kenneth W.Experience with the first three years of an accelerated dual-degree program in biomedical engineeringOur Department of Bioengineering has instituted a pilot program aimed at helping a select group of highly qualified students obtain both bachelor's and master's degrees in an accelerated timeframe-approximately four years from the beginning of their university studies. A key element of this progra...Accelerated; Dual-degrees; Education2004
8 Gesteland, Raymond F.; Atkins, John F.; Ingram, Jennifer A.; Kelly, Paul J.; Grentzmann, GuidoDual-luciferase reporter system for studying recoding signalsA new reporter system has been developed for measuring translation coupling efficiency of recoding mechanisms such as frameshifting or readthrough. A recoding test sequence is cloned in between the renilla and firefly luciferase reporter genes and the two luciferase activities are subsequently measu...Amino Acid Sequence; Genes, Reporter; HIV; Antizyme; Translation1998
9 Gesteland, Raymond F.; Atkins, John F.; Baranov, Pavel V.P-site tRNA is a crucial initiator of ribosomal frameshiftingThe expression of some genes requires a high proportion of ribosomes to shift at a specific site into one of the two alternative frames. This utilized frameshifting provides a unique tool for studying reading frame control. Peptidyl-tRNA slippage has been invoked to explain many cases of programmed ...Translation; Recoding; Kinetic Model; Frameshifting; Ribosome2004
10 Christensen, Douglas A.; Horch, Kenneth W.Accelerated dual-degree BS/MS program - experience with the first three yearsWe have initiated a pilot program that accelerates the studies of a small group of highly qualified students early in their college careers and allows them to earn both a bachelor's degree and a master's degree in about four years after starting college. It does this by introducing them early to res...Accelerated dual-degree program2004
11 Hansen, Mark S.; Healy, Lindsey J.; Johnson, Christopher R.; Capecchi, Mario R.; Keller, Charles; Jones, Greg M.Virtual histology of transgenic mouse embryos for high-throughput phenotyping.A bold new effort to disrupt every gene in the mouse genome necessitates systematic, interdisciplinary approaches to analyzing patterning defects in the mouse embryo. We present a novel, rapid, and inexpensive method for obtaining high-resolution virtual histology for phenotypic assessment of mouse ...Forkhead Transcription Factors; Paired Box Transcription Factors2006
12 Gesteland, Raymond F.; Atkins, John F.; Wills, Norma M.rRNA-mRNA base pairing stimulates a programmed -1 ribosomal frameshiftBase pairing between the 3' end of 16S rRNA and mRNA is shown to be important for the programmed -1 frameshifting utilized in decoding the Escherichia coli dnaX gene. This pairing is the same as the Shine-Dalgarno pairing used by prokaryotic ribosomes in selection of translation initiators, but for ...Frameshifting; Escherichia coli; Binding Sites; Base Composition1994
13 Gesteland, Raymond F.; Atkins, John F.Frameshifting in gene 10 of bacteriophage T7Gene 10 of bacteriophage T7, which encodes the most abundant capsid protein, has two products: a major product, 10A (36 kDa), and a minor product, 10B (41 kDa). 10B is produced by frameshifting into the -1 frame near the end of the 10A coding frame and is incorporated into the capsid. The frameshift...Frameshifting; Bacteriophage T7; RNA, Viral; Gene Expression1991
14 Gesteland, Raymond F.; Atkins, John F.; Felden, Brice; McCutcheon, John P.Probing the structure of the Escherichia coli 10Sa RNA (tmRNA)The conformation of the Escherichia coli 10Sa RNA (tmRNA) in solution was investigated using chemical and enzymatic probes. Single- and double-stranded domains were identified by hydrolysis of tmRNA in imidazole buffer and by lead(II)-induced cleavages. Ribonucleases T1 and S1 were used to map unpai...Covariation; Pseudoknot; Structural Probing; 10Sa RNA; tmRNA1997

Three types of interneurons were present in all species: tonic, which fired for the duration of the stimulus; phasic, which fire...Acoustic crabs; Neural recording; Vibration reception1976
17 Normann, Richard A.; Maynard, Edwin M.Neural interface for a cortical vision prosthesisThe development of a cortically based vision prosthesis has been hampered by a lack of basic experiments on phosphene psychophysics.
