Comments [?]

Function Required for dimerization of active 70S ribosomes into 100S ribosomes in stationary phase; 100S ribosomes are translationally inactive and sometimes present during exponential growth.
Subunit Interacts with 100S ribosomes.
Subcellular location Cytoplasm.
Similarity Belongs to the HPF/YfiA ribosome-associated protein family. Long HPF subfamily.

Comments This family does not include the short paralogs (YfiA and short HPF) found in some Proteobacteria as they have a slightly altered function. It encompasses a chloroplast-targeted protein but does not annotate it.
