Function

[IF5_YEAST] Catalyzes the hydrolysis of GTP bound to the 40S ribosomal initiation complex (40S.mRNA.Met-tRNA[F].eIF-2.GTP) with the subsequent joining of a 60S ribosomal subunit resulting in the release of eIF-2 and the guanine nucleotide. The subsequent joining of a 60S ribosomal subunit results in the formation of a functional 80S initiation complex (80S.mRNA.Met-tRNA[F]). eIF-5 is essential for cell viability.^[1]

Publication Abstract from PubMed

eIF5, a GTPase-activating protein (GAP) specific for eIF2, plays a critical role in pre-initiation complex assembly and correct AUG selection during eukaryotic translation initiation. eIF5 is involved in the formation of the multifactor complex (MFC), an important intermediate of the 43S pre-initiation complex. The C-terminal domain (CTD) of eIF5 functions as the structural core in the MFC assembly. Here we report the 1.5A crystal structure of eIF5-CTD, confirming that eIF5-CTD contains an atypical HEAT motif. In addition, analyzing the electrostatic potential and the distribution of conserved residues on the protein surface, we confirm and suggest some potential regions of interactions between eIF5-CTD and other eIFs. The structure of eIF5-CTD provides useful information in understanding the mechanism of the MFC assembly.
