You cannot be sure that this works; if the receptor is e.g. a 7 TM-helix
receptor, its expression in E. coli will be extremely bad. I don't know
about the expression of Tyr-kinase receptors in E. coli.

I am not sure if one could to expression cloning with oocytes or
something similar...

Good luck!
