Function
Activates transcription of csgD, the master regulator of biofilm formation, by binding to its promoter region (PubMed:11489123, PubMed:20874755). Also controls the transcription of cadC and ibaG (PubMed:20874755). Part of a signaling cascade that regulates curli biosynthesis. The cascade is composed of two c-di-GMP control modules, in which c-di-GMP controlled by the DgcE/PdeH pair (module I) regulates the activity of the DgcM/PdeR pair (module II), which in turn regulates activity of the transcription factor MlrA (PubMed:23708798).
