CsrC RNA binds multiple copies of CsrA, a protein that post-transcriptionally regulates central carbon flux, biofilm formation and motility in E. coli. CsrC antagonises the regulatory effects of CsrA, presumably by sequestering this protein.
The interaction between CsrC RNA and multiple copies of CsrA modulates central carbon metabolism, biofilm formation, and locomotion in E. coli. This antagonistic relationship likely prevents CsrA from exerting its regulatory influence.
