CC   -!- FUNCTION: Dual-function protein that regulates the transcription of
CC       class 2 flagellar operons and that also acts as an export chaperone for
CC       the filament-capping protein FliD. As a transcriptional regulator, acts
CC       as an anti-FlhDC factor; it directly binds FlhC, thus inhibiting the
CC       binding of the FlhC/FlhD complex to class 2 promoters, resulting in
CC       decreased expression of class 2 flagellar operons. As a chaperone,
CC       effects FliD transition to the membrane by preventing its premature
CC       polymerization, and by directing it to the export apparatus.
CC       {ECO:0000255|HAMAP-Rule:MF_01180}.
CC   -!- SUBUNIT: Homodimer. Interacts with FliD and FlhC. {ECO:0000255|HAMAP-
CC       Rule:MF_01180}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol {ECO:0000255|HAMAP-
CC       Rule:MF_01180}.
CC   -!- SIMILARITY: Belongs to the FliT family. {ECO:0000255|HAMAP-
CC       Rule:MF_01180}.
