This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center. Part of the 50S ribosomal subunit. Interacts weakly with protein L13. Belongs to the universal ribosomal protein uL6 family.
