Purification and crystallization of the yeast translation elongation factor eEF3.
A Saccharomyces cerevisiae strain expressing full-length histidine-tagged translation elongation factor 3 (eEF3) as the only form of the protein facilitated purification of the factor for both structural and functional studies. Additionally, an identical full-length form has been successfully expressed in Escherichia coli and a C-terminally truncated form of histidine-tagged eEF3 has been succe...
متن کاملCircadian clock regulation of mRNA translation through eukaryotic elongation factor eEF-2.
The circadian clock has a profound effect on gene regulation, controlling rhythmic transcript accumulation for up to half of expressed genes in eukaryotes. Evidence also exists for clock control of mRNA translation, but the extent and mechanisms for this regulation are not known. In Neurospora crassa, the circadian clock generates daily rhythms in the activation of conserved mitogen-activated p...
متن کاملEEF 1 A 1 ( eukaryotic translation elongation factor 1 alpha 1 )
The main processed mRNA encompasses exons 1, 2, 3, 4, 5, 6, 7, 8, this last can be in short or long form. In a few cases also exon 1' is retained. In a few cases exons 1 (and 1') are substituted by the alternative exon from a putative upstream minor promoter, as described above. Moreover, a quite high number of processed transcripts that, after exons 1 and 2, retain intron 2, which introduces a...
متن کاملImpaired Eukaryotic Elongation Factor 1A Expression in Alzheimer's Disease.
BACKGROUND/AIMS Recent studies have indicated a link between the impaired capacity of de novo protein synthesis and neurodegenerative diseases including Alzheimer's disease (AD). Moreover, it has been established that eukaryotic elongation factor 1A (eEF1A) plays a critical role in maintaining long-term synaptic plasticity, a cellular model for learning and memory. The aim of the present study ...
متن کاملKinetics of the interactions between yeast elongation factors 1A and 1Balpha, guanine nucleotides, and aminoacyl-tRNA.
The interactions of elongation factor 1A (eEF1A) from Saccharomyces cerevisiae with elongation factor 1Balpha (eEF1Balpha), guanine nucleotides, and aminoacyl-tRNA were studied kinetically by fluorescence stopped-flow. eEF1A has similar affinities for GDP and GTP, 0.4 and 1.1 microm, respectively. Dissociation of nucleotides from eEF1A in the absence of the guanine nucleotide exchange factor is...
