CC   -!- FUNCTION: Seems to be required for maximal rate of protein
CC       biosynthesis. Enhances ribosome dissociation into subunits and
CC       stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal
CC       subunits.
CC   -!- MISCELLANEOUS: Present with 35100 molecules/cell in log phase SD
CC       medium. {ECO:0000269|PubMed:14562106}.
CC   -!- SIMILARITY: Belongs to the eIF-1A family. {ECO:0000305}.
