Gene nameEIF5B
Protein nameEukaryotic translation initiation factor 5B (Translation initiation factor IF-2)
Eukaryotic translation initiation factor 5B (eIF-5B) (EC 3.6.5.3) (Translation initiation factor IF-2)
eIF5B protein

IF2
DescriptionFUNCTION: Plays a role in translation initiation . Ribosome-dependent GTPase that promotes the joining of the 60S ribosomal subunit to the pre-initiation complex to form the 80S initiation complex with the initiator methionine-tRNA in the P-site base paired to the start codon . Together with eIF1A (EIF1AX), actively orients the initiator methionine-tRNA in a conformation that allows 60S ribosomal subunit joining to form the 80S initiation complex . Is released after formation of the 80S initiation complex . Its GTPase activity is not essential for ribosomal subunits joining, but GTP hydrolysis is needed for eIF1A (EIF1AX) ejection quickly followed by EIF5B release to form elongation-competent ribosomes . In contrast to its procaryotic homolog, does not promote recruitment of Met-rRNA to the small ribosomal subunit . .
