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:0000250|UniProtKB:P69222}. 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:0000250|UniProtKB:P69222}. CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast CC {ECO:0000269|PubMed:11251102}. CC -!- SIMILARITY: Belongs to the IF-1 family. {ECO:0000305}.
