[[http://www.uniprot.org/uniprot/IF4E_YEAST IF4E_YEAST]] Recognizes and binds the 7-methylguanosine-containing mRNA cap during an early step in the initiation of protein synthesis and facilitates ribosome binding by inducing the unwinding of the mRNAs secondary structures. [[http://www.uniprot.org/uniprot/IF4F1_YEAST IF4F1_YEAST]] Component of the eIF4F complex, which interacts with the mRNA cap structure and serves as an initial point of assembly for the translation apparatus. Stimulates translation by interaction with polyadenylate-binding protein PAB1, bringing the 5'- and 3'-ends of the mRNA in proximity. The formation of this circular mRNP structure appears to be critical for the synergistic effects of the cap and the poly(A) tail in facilitating translation initiation, recycling of ribosomes, and mRNA stability. TIF4631 is probably essential when TIF4632 is missing.<ref>PMID:9256432</ref> <ref>PMID:10357826</ref> | |||
