Receptor for Activated protein C kinase 1 (RACK1) is a scaffold protein that has been found in association with several signaling complexes. and with the 40S subunit of the ribosome. Using the model organism Drosophila melanogaster. we recently showed that RACK1 is required at the ribosome for internal ribosome entry site (IRES)-mediated translation of viruses. https://www.chiggate.com/3m-speedglas-9002nc-welding-helmet-fashion/
