Cold shock proteins (Csps) include both cold-induced and non-cold-induced proteins. Thermus thermophilus Csp1 (ttCsp1) is a non-cold-induced Csp, whose functions remain unknown. We analyzed the oligonucleotide-binding affinities of ttCsp1, the effects of deleting ttcsp1 on transcriptome and proteome, and determined the crystal structure of ttCsp1. These results suggest that ttCsp1 functions in translation independent of transcription under optimal growth conditions.
