CC   -!- FUNCTION: Part of the ecpRABCDE operon, which encodes the E.coli common
CC       pilus (ECP). ECP is found in both commensal and pathogenic strains and
CC       plays a dual role in early-stage biofilm development and host cell
CC       recognition. Positively regulates the expression of the ecp operon (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC   -!- INDUCTION: Negatively regulated by H-NS. Positively autoregulated. Also
CC       positively regulated by IHF (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the EcpR/MatA family. {ECO:0000305}.
