CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the PtlA family. {ECO:0000305}.
CC   -!- CAUTION: B.parapertussis and B.bronchiseptica seem not to produce the
CC       pertussis toxin (S1, S2, S4, S5 and S3) and ptl proteins (PtlA, PtlB,
CC       PtlC, PtlD, PtlE, PtlF, PtlG, PtlH and PtlI) in vivo due to changes in
CC       the promoter region of the ptx-ptl operon. However, it is possible that
CC       their promoter is active under certain, as-yet-undefined conditions and
CC       that B.parapertussis and B.bronchiseptica are therefore capable of
CC       producing these proteins. {ECO:0000305}.
