1 Gesteland, Raymond F.; Atkins, John F.; Wills, Norma M.-1 frameshifting at a CGA AAG hexanucleotide site is required for transposition of insertion sequence IS1222The discovery of programmed _x0001_1 frameshifting at the hexanucleotide shift site CGA_AAG, in addition to the classical X_XXY_YYZ heptanucleotide shift sequences, prompted a search for instances among eubacterial insertion sequence elements. IS1222 has a CGA_AAG shift site. A genetic analysis re...Hexanucleotides; Heptanucleotides; Frameshifting2004
2 Gesteland, Raymond F.; Wills, Norma M.; Atkins, John F.Comparative studies of frameshifting and nonframeshifting RNA pseudoknots: a mutational and NMR investigation of pseudoknots derived from the bacteriophage T2 gene 32 mRNA and the retroviral gag-pro frameshift siteMutational and NMR methods were used to investigate features of sequence, structure, and dynamics that are associated with the ability of a pseudoknot to stimulate a "1 frameshift. In vitro frameshift assays were performed on retroviral gag-pro frameshift-stimulating pseudoknots and their derivati...Frameshifting; NMR; Pseudoknot; Retrovirus2002
3 Gesteland, Raymond F.; Atkins, John F.; Howard, Michael T.Efficient stimulation of site-specific ribosome frameshifting by antisense oligonucleotidesEvidence is presented that morpholino, 2_x0001_-O-methyl, phosphorothioate, and RNA antisense oligonucleotides can direct sitespecific âˆ'1 translational frameshifting when annealed to mRNA downstream from sequences where the P- and A-site tRNAs are both capable of re-pairing with âˆ'1 frame c...Recoding; Frameshifting; Antisense; Morpholino; Phosphorothioate; 2_x0001_-O-methyl2004
4 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
5 Gesteland, Raymond F.; Baranov, Pavel V.; Atkins, John F.Expression levels influence ribosomal frameshifting at the tandem rare arginine codons AGG_AGG and AGA_AGA in Escherichia coliABSTRACT: The rare codons AGG and AGA comprise 2% and 4%, respectively, of the arginine codons of Escherichia coli K-12, and their cognate tRNAs are sparse. At tandem occurrences of either rare codon, the paucity of cognate aminoacyl tRNAs for the second codon of the pair facilitates peptidyl-tRNA...Gene expression; Frameshifting; E. coli; Arginine codons2005
6 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
7 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
8 Gesteland, Raymond F.; Ivanov, Ivaylo P.; Atkins, John F.Programmed frameshifting in the synthesis of mammalian antizyme is +1 in mammals, predominantly +1 in fission yeast but "2 in budding yeastThe coding sequence for mammalian ornithine decarboxylase antizyme is in two different partially overlapping reading frames with no independent ribosome entry to the second ORF. Immediately before the stop codon of the first ORF, a proportion of ribosomes undergo a quadruplet translocation event t...Antizyme; Frameshifting; Ornithine decarboxylase antizyme; Recoding; S. pombe1998
9 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
10 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
11 Gesteland, Raymond F.; Atkins, John F.; Wills, Norma M.Upstream stimulators for recodingRecent progress in elucidation of 5' stimulatory elements for translational recoding is reviewed. A 5' Shine-Dalgarno sequence increases both +l and ? I frameshift efficiency in several genes; examples cited include the E. coli prfB gene encoding release factor 2 and the thuiX gene encoding the y an...Recoding; Frameshifting; Peptide factor; Stimulatory elements1995
