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}.
