UniProtKB description: Required for translation of most natural mRNAs except for leaderless mRNA. Binds mRNA upstream of the Shine-Dalgarno (SD) sequence and helps it bind to the 30S ribosomal subunit; acts as an RNA chaperone to unfold structured mRNA on the ribosome but is not essential for mRNAs with strong SDs and little 5'-UTR structure, thus it may help fine-tune which mRNAs that are translated. Unwinds dsRNA by binding to transiently formed ssRNA regions; binds about 10 nucleotides. Has a preference for polypyrimidine tracts. Negatively autoregulates its own translation.
