| + | [[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/CAF20_YEAST CAF20_YEAST]] Acts as an inhibitor of cap-dependent translation. Competes with eIF4G1/TIF4631 and EAP1 for binding to eIF4E/TIF45 and interferes with the formation of the eIF4F complex, inhibiting translation and stabilizing mRNA. Binding affinity for eIF4E/TIF45 is 10-fold less than that of eIF4G1/TIF4631. Required for induction of pseudohyphal growth in response to nitrogen limitation, probably by regulating STE12 translation.<ref>PMID:10848587</ref> <ref>PMID:12054793</ref> <ref>PMID:12406227</ref> <ref>PMID:17041186</ref> <ref>PMID:17083129</ref> <ref>PMID:9118949</ref> <ref>PMID:9707439</ref> | ||
