Translation initiation factor IF-1

UniProtKB accession:  Q5SHR1

Grouped By:  Matching UniProtKB accession

UniProtKB description:  One of the essential components for the initiation of protein synthesis. Binds in the vicinity of the A-site (PubMed:11228145). Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex.
