EIF-5A / EIF5 Protein Description
EIF-5A, also known as EIF5, plays an important role in the assembly of the 43S pre-initiation complex. In this assembly, EIF-5A interacts with eIF1 and eIF3 and binds the eIF2-GTP/Met-tRNA ternary complex along with the 40S ribosome subunit. EIF-5A is also reported to form a complex with eIF2. It is a critical component of the eIF2regulatory complex that inhibits the activity of the guanine-nucleotide exchange factor (GEF) eIF2B. This complex is suggested to serve as a cytoplasmic reservoir for eIF2 that restricts the guanine nucleotide exchange promoted by the eIF2 beta subunit for the initiation of translation.
