Her main research interest is the study of gene expression control at the post-transcriptional level in prokaryotes.
As a PhD student and post-doctoral fellow has been working on the E. coli temperate bacteriophage P4. In the lysogenic state, the expression of P4 lytic genes is prevented by a short RNA (CI RNA) that acts as an antisense RNA and induces premature transcription termination. This small RNA derives from maturation of longer transcripts. Her work contributed to clarify different aspects of the antisense RNA-dependent regulation mechanism and of the processing pathway leading to CI RNA.
Recent research interests focus on RNA maturation and turnover in E. coli. In particular, her activity has been mainly focused on an interesting enzyme, polynucleotide phosphorylase, involved in RNA degradation. Her work has contributed to elucidate relevant aspects about activity, physical and functional interaction with other proteins and physiological role of this protein in E. coli.
Currently, is also involved in a project aimed at the sRNA profiling of the opportunistic pathogen P. aeruginosa.
