Feedback-inducible nuclear-receptor-driven reporter gene expression in transgenic mice.

abstract：:There are approximately 350 non-odorant G protein-coupled receptors (GPCRs) encoded by the human genome, many of which are predicted to be potential therapeutic targets, but there are only two structures available to represent the whole of the family. We hypothesized that improving the detergent stability of these rec...
