The human genome (see Box 1.1) is composed of some 20,000 protein-coding genes and approximately the same number of genes for non-coding RNAs (ncRNAs), being used as a structural backbone of ribosomes (ribosomal RNA (rRNAs)), adaptor molecules in protein translation (transfer RNA (tRNAs)...
clearly demarcated segment of DNA, but they also led to a flurry of research activity, with scientists curious about whether the same was true in otherspecies. As other researchers were quick to discover, discontinuous gene structure and splicing duringRNA processingare the norm...
Expression of the suppressor incurs a fitness cost to the individual, csup (0 ≤ csup ≤ 1), which could arise for multiple reasons, including energy expenditure, or errors relating to the use of gene silencing machinery46,47. Gene silencing generally precedes the translation of the ...
Furthermore, it is unknown whether translation attenuation and/or transcriptional induction are protective or death inducing after ER stress. To elucidate the role of eIF2α phosphorylation and translational control in the growth and development of the mouse, we used gene targeting to mutate the Ser...

At the level of translation, then, it is expected that the deletion mutation would result in a complete lack of bovine SLC4A2 protein expression. Although this has not been confirmed in this study, much can be inferred by comparison with recent studies of SLC4A2 knockout (Ae2-/-) mice....
The raw gene expression data from the genes of interest were normalised using the geometric mean of the most stable candidate reference genes GAPDH, HPRT1, and RPL32. Depot-specific mRNA expression The present study investigated the AT depot related mRNA expression of inflammation-related genes in...
The crystal structure of Pyrococcus horikoshii Dim2 (PhDim2) has been determined in both the free state and in complex with a 3′ end fragment of 16 S rRNA and the translation initiation factor eIF2α (46, 47). We have mapped the interacting region of Krr1 and Faf1 and determined a ...
There is a regulatory approval bottleneck in the translation of the latest advances in precision cancer therapies to patients1. This has led to patients’ perception, perhaps unfairly, that regulators are unnecessarily delaying access to life saving therapies2. It is critical that regulatory frameworks...
1b). Consistent with the gene expression profile, conditional deletion of Prmt5 in Pro-B cells completely blocked B cell development (see below). However, using the CD19-cre driver, which deletes inefficiently in the BM29, allowed B cell development (Supplementary Fig. 1A). Prmt5F/F CD...
