RX PubMed=17020608; DOI=10.1186/1471-2148-6-77; RA Cai Z., Penaflor C., Kuehl J.V., Leebens-Mack J., Carlson J.E., RA dePamphilis C.W., Boore J.L., Jansen R.K.; RT "Complete plastid genome sequences of Drimys, Liriodendron, and Piper: RT implications for the phylogenetic relationships of magnoliids."; RL BMC Evol. Biol. 6:77-77(2006). 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: Plastid, chloroplast {ECO:0000255|HAMAP- CC Rule:MF_00075}. CC -!- SIMILARITY: Belongs to the IF-1 family. {ECO:0000255|HAMAP- CC Rule:MF_00075}.
