CC   -!- FUNCTION: Essential fimbrial adhesion factor that mediates binding to
CC       N-acetylglucosamine-containing receptors in the host intestinal
CC       microvilli, leading to colonization of the intestinal tissue, and
CC       diarrhea or septicemia. Also confers adhesiveness to laminin and
CC       basement membranes (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Fimbrium {ECO:0000250}. Note=Attached to the tip
CC       of the fimbrial filaments. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the fimbrial protein family. {ECO:0000305}.
