Elongation factor is a term used to describe proteins that play a critical role in the process of protein synthesis. Synonyms for elongation factor include Elongation factor 1 alpha (EF-1-alpha), Elongation factor G (EF-G), and Elongation factor Ts (EF-Ts). EF-1-alpha is responsible for the transfer of aminoacyl-tRNA to the ribosome, while EF-G and EF-Ts work together to catalyze the translocation of the ribosome along the messenger RNA (mRNA) during protein synthesis. These proteins are essential for the proper functioning of cells and organisms, and their dysregulation can have serious consequences, including disease states and developmental abnormalities.
