You are interested in studying a novel gene that appears to be involved in cancer. There is no information about the function of this gene. What would you do to obtain the cDNA for this gene? How would you express this gene and what expression systems might you utilize to study its function and why? How would determine the subcellular localization of this gene in eukaryotic cells? What are alternative methods in case one doesn’t work? How would you purify and determine the 3-dimensional structure of this protein?
