DBP1 in budding yeast
We analyzed the effect of deleting the gene encoding putative RNA helicase DBP1 in budding yeast on translational efficiencies (TEs) genome wide in wild-type or ded1-ts (temperature-sensitive allele of DED1) strains by combining ribosome footprint profiling with RNA-seq analysis of mRNA abundance.  This study includes a total of 32 samples comprised of 16 RNA-Seq samples (mRNA) and 16 ribosome footprint profiling samples (ribo). Experiment 1 includes 8 samples, comprised of 4 RNA-Seq samples and 4 ribosome footprint profiling samples, derived from 2 biological replicates each of the dbp1?  and ded1-ts dbp1? mutant strains, cultured in synthetic complete (SC) medium, following shifts in growth temperature from 30°C to 37°C for 2h.  Experiment 2 examines the effect of overexpression of DBP1 in rescuing genome-wide translational defects of a ded1-cs mutant (cold-sensitive allele of DED1) and includes 12 samples, 6 RNA-Seq samples and 6 ribosome footprint profiling samples, derived from 2 biological replicates each of WT DED1 (dubbed DED1-CS), ded1-cs and ded1-cs overexpressing DBP1 (ded1-cs_hcDBP1) strains, cultured in SC-Leu-His medium, following shifts in growth temperature from 30°C to 15°C for 10 min. Experiment 3 examines rescue of translational defects of ded1-ts by DBP1 overexpression and includes 12 samples, 6 RNA-Seq samples and 6 ribosome footprint profiling samples, derived from 2 biological replicates each of WT DED1(DED1-TS), ded1-ts and ded1-ts overexpressing DBP1 (ded1-ts_hcDBP1) strains, cultured in SC-Leu-His medium, following shifts in growth temperature from 30°C to 37°C for 2h. Overall design: 32 samples
