WebJan 19, 2024 · Translation elongation is a key step of protein synthesis, during which the nascent polypeptide chain extends by one amino acid residue during one elongation cycle. More and more data revealed that the elongation is a key regulatory node for translational control in health and disease. During elongation, elongation factor Tu (EF-Tu, eEF1A … WebThis is not unreasonable considering that transcription elongation and termination are two sides of the same coin. As for the roles of protein factors in elongation control, transcription elongation factors for RNA polymerase II have been extensively characterized (Table 1). How some of these factors function is detailed below.
WebDefinition. Elongation factor-Tu (EF-Tu, bacterial)/eukaryotic elongation factor 1α (eEF1α also known as eEF1A) is a critical factor for protein synthesis and is highly conserved across all three domains of life. EF-Tu/eEF1α is a principal member of the homologous translational GTPase family. Among the members of the family, eEF1α-related ...
