One of at least 4 proteins (Era, RbfA, RimM and RsgA/YjeQ) that assist in the late assembly stage of the 30S ribosomal subunit. An accessory protein needed during the final step in assembly of the 30S ribosomal subunit, for assembly of the head region (the 16S rRNA 3' domain) (PubMed:11514519, PubMed:15496525, PubMed:20188109, PubMed:23611982, PubMed:27382067). It may act while Era is associated and before RimP in 30S subunit assembly (PubMed:20188109). Interacts with S19 (PubMed:15496525). Essential for efficient processing of 16S rRNA; a deletion mutant accumulates 17S rRNA (PubMed:9422595). Deletions also do not assemble the head-associated ribosomal proteins correctly (PubMed:23611982, PubMed:27382067). May be needed both before and after RbfA during the maturation of 16S rRNA. It has affinity for free ribosomal 30S subunits but not for 70S ribosomes (PubMed:9226267).

Belongs to the RimM family.
