RACK1 and infection: As expected, most ribosomal proteins remained unchanged upon infection; however we surprisingly identified 11 ribosomal proteins as significantly increased on ribosomes, including the large subunit proteins rpL40, rpL9, rpL32, rpL13, and rpL37, and the small subunit proteins RACK1, rpS21, rpS6, rpS3, rpS11, rpS12 (Fig. 1B).
