Omnipotent role of archaeal elongation factor 1 alpha (EF1α in translational elongation and termination, and quality control of protein synthesis.
The molecular mechanisms of translation termination and mRNA surveillance in archaea remain unclear. In eukaryotes, eRF3 and HBS1, which are homologous to the tRNA carrier GTPase EF1α, respectively bind eRF1 and Pelota to decipher stop codons or to facilitate mRNA surveillance. However, genome-wide searches of archaea have failed to detect any orthologs to both GTPases. Here, we report the crys...

متن کاملProtein synthesis in yeast. Structural and functional analysis of the gene encoding elongation factor 3.
The yeast translational elongation factor 3 (EF-3) stimulates EF-1 alpha-dependent binding of aminoacyl-tRNA by the ribosome. The requirement for EF-3 is unique to fungi; a functional analog has not been found in prokaryotes or other eukaryotes. We have isolated and characterized the structural gene, YEF3, that encodes EF-3. The YEF3 gene is present in one copy/haploid genome and is essential f...
متن کاملSelenocysteine tRNA-specific elongation factor SelB is a structural chimaera of elongation and initiation factors.
In all three kingdoms of life, SelB is a specialized translation elongation factor responsible for the cotranslational incorporation of selenocysteine into proteins by recoding of a UGA stop codon in the presence of a downstream mRNA hairpin loop. Here, we present the X-ray structures of SelB from the archaeon Methanococcus maripaludis in the apo-, GDP- and GppNHp-bound form and use mutational ...
متن کاملElongation factor-1 alpha is an overexpressed actin binding protein in metastatic rat mammary adenocarcinoma.
Overexpression of elongation factor-1 alpha (EF1 alpha) mRNA has been correlated with increased metastatic potential in mammary adenocarcinoma; however, this relationship was not explored at the level of protein expression. As EF1 alpha has been shown in other cell types to be a component of the actin cytoskeleton, a likely effector in metastasis, the actin binding activity of EF1 alpha from me...
