It's hard to prove a negative but.... No one in "mainstream" neuroscience or cell biology takes these proposals seriously. Hameroff and Penrose have proposed some possible mechanisms (e.g., dendritic lamellar bodies), but none of these have panned out experimentally; for example, the DLBs are in the wrong place. They keep revising the theory around these data, but I think a lot of experimentalists have lost interest. I gather there are other more philosophical/first principles arguments against this too. It would be neat if it were true though....
