CC   -!- FUNCTION: One of the essential components for the initiation of protein
CC       synthesis. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit
CC       to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps
CC       modulate mRNA selection, yielding the 30S pre-initiation complex (PIC).
CC       Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are
CC       released leaving the mature 70S translation initiation complex.
CC       {ECO:0000255|HAMAP-Rule:MF_00075}.
CC   -!- SUBUNIT: Component of the 30S ribosomal translation pre-initiation
CC       complex which assembles on the 30S ribosome in the order IF-2 and IF-3,
CC       IF-1 and N-formylmethionyl-tRNA(fMet); mRNA recruitment can occur at
CC       any time during PIC assembly. {ECO:0000255|HAMAP-Rule:MF_00075}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00075}.
CC   -!- SIMILARITY: Belongs to the IF-1 family. {ECO:0000255|HAMAP-
CC       Rule:MF_00075}.
