Has anybody else heard of this gene? I found out about it a couple months back and have been doing research on it. However, I can't seem to find any websites that gives me a clear explanation on the experiment or how it works in greater detail. It only tells me that it's located on Chromosome 15 and that the gene increases nicotine receptor. Yes, but what is the name of the receptor? What enzymes and proteins are involved? What metabolic reactions occur? Can anybody direct me to any good websites with documented papers on the experiment or papers published by the researchers themselves or have any hypothesis on how this gene functions?
