More than ten different protein factors are involved in initiation of protein synthesis in eukaryotes. For binding of initiator tRNA and mRNA to the 40S ribosomal subunit, the initiation factors eIF-2 and eIF-3 are particularly important. They consist of several different subunits and form stable complexes with the 40S ribosomal subunit. The location of eIF-2 and eIF-3 in these complexes as well as the interactions of the individual components have been analyzed by biochemical methods and… CONTINUE READING
