RT   coding plausible membrane protein.";
RL   Submitted (MAY-1995) to the EMBL/GenBank/DDBJ databases.
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 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the FliQ/MopD/SpaQ family. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAA09163.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
