Synonyms for the term "Eukaryotic Initiation Factor" include EIF, initiation factor, and eIF. In molecular biology, these terms refer to a class of proteins involved in the initiation of protein synthesis in eukaryotic organisms. EIFs play a crucial role in binding mRNA, recruiting ribosomes, and facilitating the assembly of the translation initiation complex. By promoting the start of protein synthesis, these factors play a key regulatory role in gene expression. They are essential for the proper functioning of cells and are often associated with various diseases, making them a focus of research in biomedicine.
