Function
[I7MK25_TETTS] Seems to be required for maximal rate of protein biosynthesis. Enhances ribosome dissociation into subunits and stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal subunits (By similarity).[RuleBase:RU004365] [E6PBR9_TETTH] Required for the assembly and/or stability of the 40S ribosomal subunit. Required for the processing of the 20S rRNA-precursor to mature 18S rRNA in a late step of the maturation of 40S ribosomal subunits (By similarity).[HAMAP-Rule:MF_03015]
Publication Abstract from PubMed
Eukaryotic translation initiation factors (eIFs) 1A and 1 are central players in the complex process of start-codon recognition. To improve mechanistic understanding of this process, we determined the crystal structure of the 40S ribosomal subunit in complex with eIF1A and eIF1 from Tetrahymena thermophila at a resolution of 3.7 A. It reveals the positions of the two factors on the 40S and the conformational changes that accompany their binding.
