Eukaryotic translation initiation factor (with specific subtypes: eIF4E, eIF4G, eIF2, etc.) (eIF (for the family); commonly used forms include eIF4E, eIF4G, eIF2, eIF3, etc.)

Eukaryotic translation initiation factors are essential proteins required to initiate the translation of messenger RNA into protein in eukaryotic organisms. They regulate the recruitment and positioning of ribosomes, the initiator tRNA, and mRNA at the correct start codon, enabling the assembly of elongation-competent ribosomes and the beginning of protein synthesis. These factors are tightly regulated, often through phosphorylation and protein-protein interactions, and represent critical control points for overall gene expression. Abnormal activity or regulation of these factors is linked to diseases such as cancer and infection, and their modulation is a promising therapeutic strategy
