The WD repeat-containing protein receptor for activated protein kinase C (RACK)-1 has been linked to a variety of signaling systems including protein kinase C, growth factors, and IFNs. In the IFN system, RACK-1 functions as an adaptor recruiting the transcription factor STAT1 to the receptor complex. However, RACK-1 should play a broader role in type I IFN signaling because mutation of the RACK-1 binding site in the IFN-alpha receptor 2/beta subunit of the type I IFN receptor abrogates not only STAT1, but also STAT2, activation. In this study, we demonstrate that RACK-1 serves as a scaffold protein for a multiprotein complex that includes the IFN-alpha receptor 2/beta-chain of the receptor, STAT1, Janus kinase 1, and tyrosine kinase 2. In vitro data further suggest that within this complex tyrosine kinase 2 is the tyrosine kinase responsible for the phosphorylation of STAT1. Finally, we provide evidence that RACK-1 may also serve as a scaffold protein in other cytokine systems such as IL-2, IL-4, and erythropoietin.
