DUF3268 RNAs are consistently found in the 3' untranslated regions (UTRs) of operons that include genes which encode the conserved protein domain DUF3268, sigma factors and signal peptidases. This genetic location could suggest that DUF3268 are cis-regulatory elements. However, it is unusually for cis regulators to be present in 3' UTRs in bacteria. Therefore it is also possible that DUF3268 RNAs function as small RNAs. Predicted Rho-independent transcription terminators are often located nearby to (10-40) and downstream of DUF3268 RNAs. These transcription terminators are consistent with both the hypothesis of cis-regulatory function and function as a small RNA.
