Good news for "wusses": Research links pain sensitivity to gene
...says, that as in mice, the variations among people lie instead in the regulatorypart of the gene. PET scans in other labs at Hopkins have shown that the number of mureceptors in humans can differ dramatically: Some people have almost two timesmore mu receptors in certain brain areas than others. ...Scientists discover second gene for disorder described by Darwin
...e same disorder? Again, says Zonana, theanswer may lie in the projected structures of the protein products. Theproteins coded by the ED1 and DL genes bear similarities to a signaling molecule(the ED1 protein) and its receptor (the DL protein). The researchers proposethat both proteins may interact with ...Single switch triggers two immune system genes
..." The key to the genes' long-lived marriage might lie in the mechanism by whichthe control sequence activates both genes at once, said Nussenzweig.

...re indeed bitter receptors, but the ultimate tests lie with living organisms. Two strains of mice, bitter "tasters" and "non-tasters," were found to have distinct differences in the gene for a bitter receptor.
