Ltv1 Is Required for Efficient Nuclear Export of the Ribosomal Small Subunit in Saccharomyces cerevisiae
In eukaryotes, 40S and 60S ribosomal subunits are assembled in the nucleus and exported to the cytoplasm independently of one another. Nuclear export of the 60S requires the adapter protein Nmd3, butExpand

Using a Saccharomyces cerevisiae strain containing an integrated copy of an H2A-lacZ fusion gene, we screened for mutants which overexpressed beta-galactosidase as a way to identify genes whichExpand

Differential effects of Cdc68 on cell cycle-regulated promoters in Saccharomyces cerevisiae.
Swi4 and Swi6 form a complex which is required for Start-dependent activation of HO and for high-level expression of G1 cyclin genes CLN1 and CLN2. To identify other regulators of this pathway, weExpand

Genetic Analysis of the Ribosome Biogenesis Factor Ltv1 of Saccharomyces cerevisiae
Ribosome biogenesis has been studied extensively in the yeast Saccharomyces cerevisiae. Yeast Ltv1 is a conserved 40S-associated biogenesis factor that has been proposed to function in small subunitExpand

Genetic and Biochemical Interactions Among Yar1, Ltv1 and RpS3 Define Novel Links Between Environmental Stress and Ribosome Biogenesis in Saccharomyces cerevisiae
In the yeast S. cerevisiae, ribosome assembly is linked to environmental conditions by the coordinate transcriptional regulation of genes required for ribosome biogenesis. In this study we show thatExpand

Dominant Mutations in the Late 40S Biogenesis Factor Ltv1 Affect Cytoplasmic Maturation of the Small Ribosomal Subunit in Saccharomyces cerevisiae
In eukaryotes, 40S and 60S ribosomal subunits are assembled in the nucleus from rRNAs and ribosomal proteins, exported as premature complexes, and processed in final maturation steps in theExpand

Role of transcriptional and posttranscriptional regulation in expression of histone genes in Saccharomyces cerevisiae.
We analyzed the role of posttranscriptional mechanisms in the regulation of histone gene expression in Saccharomyces cerevisiae. The rapid drop in histone RNA levels associated with the inhibition ofExpand

Characterization of the 5' termini of purified nascent simian virus 40 late transcripts.
The primary transcripts of simian virus 40 are extensively processed in the nuclei of infected monkey cells before they are transported to the cytoplasm as mature mRNAs. To investigate the earlyExpand

A new Saccharomyces cerevisiae ankyrin repeat-encoding gene required for a normal rate of cell proliferation.
We have characterized a new ankyrin (ANK) repeat-containing Saccharomyces cerevisiae gene, YAR1, located between the HSP82 and SUI3 genes on chromosome XVI. YAR1 encodes a 200-amino-acid (aa) proteinExpand

Mutation and modeling analysis of the Saccharomyces cerevisiae Swi6 ankyrin repeats.
The Swi4-Swi6 family of transcription factors confers G1/S specific transcription in budding and fission yeast. These proteins contain four ankyrin repeats, which are present in a large number ofExpand
