Receptor of activated protein C kinase 1 (RACK1)

Scaffolding protein involved in the recruitment, assembly and/or regulation of many different signaling molecules. Interacts with a huge selection of proteins and plays a role in many cellular processes.

Part of the 40S ribosomal subunit involved in translational repression (PubMed:23636399). Involved from the initiation of the ribosome quality control (RQC), a pathway that happens when a ribosome has stalled during translation, by promoting ubiquitination of a subset of 40S ribosomal subunits (PubMed:28132843).
