Human Eukaryotic Translation Elongation Factor 1 Gamma (EEF1g) Protein

Background

EEF1G is a structural subunit of the eukaryotic elongation factor 1 (eEF1) complex, which mediates the delivery of aminoacyl-tRNA to the ribosome during protein elongation. Unlike other subunits, EEF1G plays a scaffolding role, stabilizing the eEF1 complex and enabling interactions with additional proteins involved in translation, signal transduction, and cellular metabolism. EEF1G is also implicated in translational regulation under stress conditions, where it interacts with molecular chaperones and other protein complexes to maintain translation fidelity and protein stability. Elevated expression of EEF1G has been associated with cancer progression, particularly in breast, colorectal, and liver cancers, where it contributes to enhanced protein synthesis, cell proliferation, and survival. Its role as a scaffold protein highlights its significance in coordinating protein synthesis and cellular signaling pathways critical for growth and stress adaptation.
