Description: OABK is a small molecule switch that can be used to control protein activity. Genetic encoding of OABK using a pyrrolysyl tRNA synthetase/tRNACUA pair in mammalian cells enables the site-specific introduction of a small molecule-removable protecting group into the protein of interest. A phosphine-mediated Staudinger reduction is used to re-activate protein function.
