Ribosomal proteins (r-proteins) are constituents of the ribosome, the organelle in the cell that provides the translation of the genetic message into proteins. The r-protein number varies from about 55 to more than 70 in different organisms. Together with 3–4 ribosomal RNA strains (rRNAs) they constitute the two subunits of the ribosome, the small and the large subunits. By specific interaction the r-proteins are bound to the rRNAs and the neighbouring proteins of the organelle and constitute together the protein biosynthesis machinery of the cell.
