where is ribosomal protein made
As the sites of protein synthesis, they are essential parts of the cell. In mammals, ribosomes are composed 4 types of rRNA and around 80 different proteins. In mammalian cells, ribosomal proteins can compose up to 15% of a cellâs total protein and 7-9% of the mRNAs which are made. It seems that these proteins are expressed in about equal amounts in cells.
