The che1 RNA motif is a conserved RNA structure that was discovered by bioinformatics.[1] che1 motifs are found in the genus Streptomyces, as well as some other organisms that are closely related to this genus.

It is ambiguous whether che1 RNAs function as cis-regulatory elements or whether they operate in trans. However, che1 RNAs are consistently located upstream of protein-coding genes, which are often predicted to function as cholesterol esterases. It is possible that che1 RNAs regulate these genes.
