| Post Translational Modifications | ISGylated. Phosphorylated by TXK. Phosphorylation by PASK increases translation efficiency. Phosphorylated by ROCK2. Phosphorylation by TGFBR1 inhibits translation elongation. Trimethylated at Lys-79 by EEF1AKMT1. Methylated at Lys-165 by EEF1AKMT3, methylation by EEF1AKMT3 is dynamic as well as inducible by stress conditions, such as ER-stress, and plays a regulatory role on mRNA translation. Trimethylated at Lys-318 by EEF1AKMT2. Mono-, di-, and trimethylated at Lys-36 by EEF1AKMT4.trimethylated form is predominant. Methylation by EEF1AKMT4 contributes to the fine-tuning of translation rates for a subset of tRNAs. Trimethylated at Gly-2 by METTL13. Mono- and dimethylated at Lys-55 by METTL13.dimethylated form is predominant. Ubiquitinated at Lys-385 by RNF14 in response to ribosome collisions (ribosome stalling), leading to its degradation by the proteasome and rescue of stalled ribosomes. |
| Function | Translation elongation factor that catalyzes the GTP-dependent binding of aminoacyl-tRNA (aa-tRNA) to the A-site of ribosomes during the elongation phase of protein synthesis. Base pairing between the mRNA codon and the aa-tRNA anticodon promotes GTP hydrolysis, releasing the aa-tRNA from EEF1A1 and allowing its accommodation into the ribosome. The growing protein chain is subsequently transferred from the P-site peptidyl tRNA to the A-site aa-tRNA, extending it by one amino acid through ribosome-catalyzed peptide bond formation. Also plays a role in the positive regulation of IFNG transcription in T-helper 1 cells as part of an IFNG promoter-binding complex with TXK and PARP1. Also plays a role in cytoskeleton organization by promoting actin bundling. (Microbial infection) Required for the translation of viral proteins and viral replication during human coronavirus SARS-CoV-2 infection. |
