CC -!- FUNCTION: Required for surface presentation of invasion plasmid
CC antigens. Could play a role in preserving the translocation competence
CC of the ipa antigens. Required for invasion and for secretion of the
CC three ipa proteins.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the FliR/MopE/SpaR family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAK18474.1; Type=Erroneous initiation; Evidence={ECO:0000305};
