Synthesis of epidermal growth factor (EGF) receptor in vitro using SP6 RNA polymerase-transcribed template mRNA.

The epidermal growth factor (EGF) receptor plays a key role in the control cellular proliferation, and its homology to the avian erythroblastosis virus erb B oncogene implicates its involvement in cellular transformation. The establishment of a correlation between the various structural domains of the EGF receptor and their functional counterparts would greatly advance our understanding of these processes. To this end, we have constructed an expression vector containing the SP6 viral promoter and an adjacent cDNA fragment encoding the full-length EGF receptor. Upon addition of SP6 RNA polymerase, this DNA is capable of generating large amounts of EGF receptor mRNA; this RNA can then be translated in vitro into immunoprecipitable EGF receptor protein. The translational efficiency of this EGF receptor RNA was found to be relatively low: approx. 100-fold lower than globin RNA synthesized using SP6 RNA polymerase. Use of these tools should now permit the synthesis and analysis of mutated EGF receptor protein in an effort to clarify the role of this receptor in growth control.[1]
