In cell biology and pharmacology, small chemicals are mostly used as agonists and antagonists against receptors and enzymes. The immunosuppressant rapamycin can serve an entirely different purpose: if employed sensibly, it might function as an inducer of dimerization that is able to rapidly activate enzyme activity inside the intact cell. A number of very recent developments such as photoactivatable derivatives make rapamycin an even more attractive tool for basic science. © 2012 Federation of European Biochemical Societies.
