Contributors: S. Boulanger*, S. Belcher*, U. Schmidt*, S. Dib-Hajj*, T. Schmidt* & P. Perlman*

MeSH headings : Base Composition; Base Sequence; Conserved Sequence; DNA Mutational Analysis; Electron Transport Complex IV / genetics; Introns / genetics; Molecular Sequence Data; Phenotype; Point Mutation; RNA Splicing; RNA, Catalytic / genetics; Saccharomyces cerevisiae / genetics; Structure-Activity Relationship; Suppression, Genetic
TL;DR: Intra-D5 second-site suppressors showed that pairing between nucleotides at positions 2 and 33 and 4 and 31 is especially important for D5 function, and the hypothesis of Madhani and Guthrie that helix 1 formed between yeast U2 and U6 small nuclear RNAs may be the spliceosomal cognate of D5 is discussed.

1995 journal article

The responsiveness of a tetracycline-sensitive expression system differs in different cell lines

Journal of Biological Chemistry, 270(23), 14168–14174.

By: J. Howe*, B. Skryabin*, S. Belcher*, C. Zerillo* & C. Schmauss*

Contributors: J. Howe*, B. Skryabin*, S. Belcher*, C. Zerillo* & C. Schmauss*

MeSH headings : Animals; Cell Line; Gene Expression Regulation / drug effects; Humans; RNA, Messenger / analysis; Rats; Receptors, Dopamine / genetics; Receptors, Dopamine D2; Receptors, Dopamine D3; Tetracycline / pharmacology; Transfection
TL;DR: HEK 293 cells do not provide a cellular environment in which the expression of a heterologous gene can be tightly controlled in a tetracycline-responsive manner, and in the induced state, its mRNA levels were found to be very low in GH3 cells and very high in HEk 293 cells.

1994 journal article

Splicing defective mutants of the COXI gene of yeast mitochondrial DNA: Initial definition of the maturase domain of the group II intron AI2

Nucleic Acids Research, 22(11), 2057–2064.

By: J. Moran*, K. Mecklenburg*, P. Sass*, S. Belcher*, D. Mahnke*, A. Lewin*, P. Perlman*

Contributors: J. Moran*, K. Mecklenburg*, P. Sass*, S. Belcher*, D. Mahnke*, A. Lewin*, P. Perlman*

MeSH headings : Base Sequence; DNA, Fungal; DNA, Mitochondrial / genetics; Electron Transport Complex IV / genetics; Endoribonucleases / metabolism; Genes, Fungal; Genetic Complementation Test; Introns; Molecular Sequence Data; Mutation; Nucleotidyltransferases / metabolism; Open Reading Frames; RNA Splicing / genetics; RNA, Fungal; Restriction Mapping; Saccharomyces cerevisiae / genetics
TL;DR: Six mutations blocking the function of a seven intron form of the mitochondrial gene encoding subunit I of cytochrome c oxidase (COXI) and mapping upstream of exon 3 were isolated and characterized and a trans-recessive mutant confirms that the intron 1 reading frame encodes a maturase function.

1992 journal article

A maturase-encoding group MA intron of yeast mitochondria self-splices in vitro

Nucleic Acids Research, 20(7), 1747–1754.

By: S. Hebbar, S. Belcher* & P. Perlman*

Contributors: S. Hebbar, S. Belcher* & P. Perlman*

MeSH headings : Base Sequence; DNA, Mitochondrial / genetics; Introns / genetics; Mitochondria / enzymology; Molecular Sequence Data; RNA Splicing / genetics; RNA, Catalytic / metabolism; Yeasts / genetics
TL;DR: This is the first report of a maturase-encoding intron of either group I or group II that self-splices in vitro, and it requires much higher levels of Mg2+ and added salts for ready detection of splicing activity. (via Semantic Scholar)
