Organism

Status

Functioni

This protein promotes the GTP-dependent binding of aminoacyl-tRNA to the A-site of ribosomes during protein biosynthesis. With PARP1 and TXK, forms a complex that acts as a T helper 1 (Th1) cell-specific transcription factor and binds the promoter of IFN-gamma to directly regulate its transcription, and is thus involved importantly in Th1 cytokine production.1 Publication

Post-translational modificationi

ISGylated.1 Publication
Phosphorylated by TXK. Phosphorylation by PASK increases translation efficiency. Phosphorylated by ROCK2 (PubMed:26497934).4 Publications
Trimethylated at Lys-79 by EEF1AKMT1 (PubMed:26545399). 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 (PubMed:28108655). Trimethylated at Lys-318 by EEF1AKMT2 (PubMed:25144183). 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 (PubMed:28520920).4 Publications

Interactioni

Subunit structurei

Found in a nuclear export complex with XPO5, EEF1A1, Ran and aminoacylated tRNA. Interacts with PARP1, TXK, XPO5 and KARS. May interact with ERGIC2. Interacts with IFIT1 (via TPR repeats 4-7) (By similarity). Interacts with DLC1, facilitating distribution to the membrane periphery and ruffles upon growth factor stimulation. Interacts with ZPR1; the interaction occurs in a epidermal growth factor (EGF)-dependent manner. Interacts with PPP1R16B (PubMed:26497934).By similarity8 Publications
