| + | [[http://www.uniprot.org/uniprot/IF2A_YEAST IF2A_YEAST]] eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B. [[http://www.uniprot.org/uniprot/EI2BD_SCHPO EI2BD_SCHPO]] Catalyzes the exchange of eukaryotic initiation factor 2-bound GDP for GTP. [[http://www.uniprot.org/uniprot/EI2BA_SCHPO EI2BA_SCHPO]] Catalyzes the exchange of eukaryotic initiation factor 2-bound GDP for GTP. [[http://www.uniprot.org/uniprot/EI2BG_SCHPO EI2BG_SCHPO]] Catalyzes the exchange of eukaryotic initiation factor 2-bound GDP for GTP.
