CC   -!- FUNCTION: Part of the yfcOPQRSUV fimbrial operon. Could contribute to
CC       adhesion to various surfaces in specific environmental niches.
CC       Increases adhesion to eukaryotic T24 bladder epithelial cells in the
CC       absence of fim genes. {ECO:0000269|PubMed:20345943}.
CC   -!- INDUCTION: Expression is negatively regulated by H-NS and subjected to
CC       cAMP receptor protein (CRP)-mediated catabolite repression.
CC       {ECO:0000269|PubMed:20345943}.
CC   -!- DISRUPTION PHENOTYPE: Deletion of the operon under classical laboratory
CC       conditions does not result in any major effect on E.coli capacity to
CC       form biofilms compared with the wild-type strain.
CC       {ECO:0000269|PubMed:20345943}.
CC   -!- MISCELLANEOUS: The operon is cryptic under classical laboratory
CC       conditions, but is functional when constitutively expressed.
CC       {ECO:0000305|PubMed:20345943}.
CC   -!- SIMILARITY: Belongs to the fimbrial protein family. {ECO:0000305}.
