Proteins14
Recent proteomic studies in Saccharomyces cerevisiae have identified nearly 200 proteins, other than the structural ribosomal proteins, that participate in the assembly of ribosomal subunits and their transport from the nucleus. (biomedcentral.com)
Although eukaryotic ribosomes are composed of only four ribosomal RNAs (rRNAs) and around 80 ribosomal proteins, many other proteins are recruited to help deliver ribosomal subunits to the cytoplasm - at the rate of 2,000 or so ribosomes each minute in a growing yeast cell, for example [ 2 , 3 ]. (biomedcentral.com)
