TranscriptomicsDeep sequencing reveals mRNA recruitment in translation initiation
We studied the initiation signals located in the translational initiation region (TIR) and identified the role for recognition of the initiation signals in each individual stage during formation of the initiation complexes. Sequencing the randomized mRNA libraries captured by translation initiation ...

TranscriptomicsGlucose depletion inhibits translation initiation in yeast - transcription profiling
This is a transcription profiling study on yeast undergoing glucose depletion. It reveals that glucose depletion inhibits translation initiation in a mechanism involving eIF4A loss and 48S pre-initiation complex accumulation, while the pentose phosphate pathway is co-ordinately up-regulated

TranscriptomicsGlucose depletion inhibits translation initiation in yeast - polysome and monosome profiling
This is a polysome/monosome profiling study on yeast undergoing glucose depletion. Polysomes and monosomes are extracted and the transcripts bound to each fraction are measured by microarray. The study reveals that glucose depletion inhibits translation initiation in a mechanism involving eIF4A loss...

TranscriptomicseIF3a in Urinary Bladder Cancer M-bM-^@M-^S in vivo and in vitro insights
The eukaryotic translation initiation factor (eIF) 3a is described in various tumor entities as potential tumor marker involved in development and progression of cancer. eIF3a is the largest subunit of the eIF3 complex, a key functional entity in 80S establishment and translation initiation. We hypo...

ProteomicsConformational rearrangements upon start codon recognition in human 48S translation initiation complex
Selection of the translation start codon is a key step during protein synthesis in human cells. We obtained cryo-EM structures of human 48S initiation complexes and characterized the intermediates of codon recognition by kinetic methods using eIF1A as a reporter. Both approaches capture two distinct...

Transcriptomicsm6A in 5’ untranslated regions promotes cap-independent translation of mRNA
N6-methyladenosine (m6A) is a widespread internal RNA modification whose function is poorly understood. Here we report that m6A residues within the 5'UTR promote a novel form of cap-independent translation which is mediated through an interaction between m6A residues and the translation initiation f...

TranscriptomicsTranscription profiling of Arabidopsis polysomal and non-polysomal RNA samples isolated from 10-day-old wild-type and eif3h mutant plants
Microarray comparisons of polysome loading in wild-type Arabidopsis and eif3h mutant; Goal: ; To find the target mRNAs that are translationally regulated by eIF3h. BACKGROUND: The eukaryotic translation initiation factor eIF3 has multiple roles during the initiation of translation of cytoplasmic mRN...

ProteomicsElucidation of the translation initiation factor interaction network of Haloferax volcanii reveals coupling of transcription and translation in haloarchaea
Translation is an important step in gene expression. Initiation of translation is rate-limiting, and it is 13 phylogenetically more diverse than elongation or termination. Bacteria contain only three initiation 14 factors. In stark contrast, eukaryotes contain more than 10 (subunits of) initiation f...

TranscriptomicsTranscription profiling of Arabidopsis eif3h mutants vs. wild type
Microarray comparisons of transcript level in wild-type Arabidopsis and eif3h mutant plants. Goal:; To detect any change in transcript level between WT and eif3h mutant.

TranscriptomicsTemporally defined neocortical translation and polysome assembly is determined by the RNA-binding protein, Hu antigen R
Precise spatiotemporal control of mRNA translation machinery is essential to proper development of highly complex systems like the neocortex. Here, we show that an RNA-binding protein, Hu antigen R (HuR), regulates both neocorticogenesis and specificity of neocortical translation machinery in a deve...
