CC -!- FUNCTION: Binds to RNA polymerase (RNAP), probably stimulating
CC transcriptions from principal, but not alternative sigma factor
CC promoters (By similarity). Partially restores transcription in the
CC presence of rifampicin (Rif) in vitro; overexpression leads to an
CC increase in the Rif tolerance in vivo, with smaller colonies. Seems to
CC act by removing Rif from its binding site and preventing its further
CC binding. No longer stimulates transcription in Rif-resistant RNA
CC polymerase (with mutations in rpoB). {ECO:0000250,
CC ECO:0000269|PubMed:19926651, ECO:0000269|PubMed:21415119}.
CC -!- SUBUNIT: Monomer. Forms a complex with the RNAP catalytic core,
CC specifically with the beta subunit (RpoB); its binding site may overlap
CC with that of Rif. May bind free principal sigma factors.
CC -!- INDUCTION: Constitutively expressed during growth, increases slightly
CC in stationary phase (at protein level). {ECO:0000269|PubMed:19926651}.
CC -!- SIMILARITY: Belongs to the RNA polymerase-binding protein RbpA family.
CC {ECO:0000255|HAMAP-Rule:MF_01483}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABK74095.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
