This protein binds directly to 23S ribosomal RNA. Contacts the 16S rRNA of the 30S subunit in two different positions helping to form bridges B5 and B8. Part of the 50S ribosomal subunit. Contacts protein L19. Forms a bridge to the 30S subunit in the 70S ribosome, contacting the 16S rRNA. Belongs to the universal ribosomal protein uL14 family.
