Ribosomal protein S16 is one of the proteins from the small ribosomal subunit. It belongs to a ribosomal protein family that is divided into three groups based on sequence similarity: * Eubacterial S16. * Algal and plant chloroplast S16. * Cyanelle S16. * Neurospora crassa mitochondrial S24 (cyt-21). S16 proteins have about 100 amino-acid residues. There are two paralogues in Arabidopsis thaliana, RPS16-1 (chloroplastic) and RPS16-2 (targeted to the chloroplast and the mitochondrion) RPS16 has been shown to interact with
