CC   -!- FUNCTION: During stationary phase, promotes and stabilizes dimerization
CC       of 70S ribosomes by the ribosome modulation factor (RMF), leading to
CC       the formation of inactive 100S ribosomes.
CC       {ECO:0000250|UniProtKB:P0AFX0}.
CC   -!- SUBUNIT: Associates exclusively with 100S ribosomes, which are dimers
CC       of 70S ribosomes. {ECO:0000250|UniProtKB:P0AFX0}.
CC   -!- SIMILARITY: Belongs to the HPF/YfiA ribosome-associated protein family.
CC       Short HPF subfamily. {ECO:0000305}.
