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. Major subunit of the fimbria (By similarity).
CC       {ECO:0000250}.
CC   -!- SUBUNIT: Self-associates. Forms filaments. Interacts with EcpD.
CC       {ECO:0000269|PubMed:22355107}.
CC   -!- SUBCELLULAR LOCATION: Fimbrium {ECO:0000250}.
CC   -!- INDUCTION: Negatively regulated by H-NS. Positively regulated by IHF
CC       and EcpR. {ECO:0000269|PubMed:22797761}.
CC   -!- SIMILARITY: Belongs to the EcpA/MatB fimbrillin family. {ECO:0000305}.
