Web19 de abr. de 2002 · Viral Recruitment of Ribosomes. The unique features of the eukaryotic ribosome, located primarily on its outer solvent-exposed surfaces, are prime targets for interaction with regulatory factors. These surfaces can also be exploited by viruses for ribosome recruitment during host cell infection. WebRibosomes are the site of protein synthesis. The proteins synthesized in the cytoplasm are utilized in the cytoplasm itself, the proteins synthesized by bound ribosomes are transported outside the cell. Also Read: Cells.
