Required for post-transcription initiation control of the comE operon. Promotes the accumulation of its target comE mRNA to septal and polar sites. Interacts directly with DivIVA. Localizes to the division site and cell poles, in a DivIVA-dependent manner. Polar localization is not essential for competence development. Disruption results in severely reduced transformation frequency, but has no detectable effect on either the frequency or the location of division septa.
