RT physiological diversity.";
RL Genome Res. 12:532-542(2002).
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 (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the eIF-1A family. {ECO:0000305}.
