CC   -!- FUNCTION: RNA chaperone with significant RNA binding, RNA strand
CC       exchange and RNA duplexing activities. May regulate ProP activity
CC       through an RNA-based, post-transcriptional mechanism.
CC       {ECO:0000255|HAMAP-Rule:MF_00749}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00749}.
CC   -!- SIMILARITY: Belongs to the ProQ family. {ECO:0000255|HAMAP-
CC       Rule:MF_00749}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAP16891.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
