PROMOTER FOR THE FUNCTIONAL CHARACTERISATION OF G-PROTEIN COUPLED RECEPTORS IN THE YEAST SACCHAROMYCES CEREVISIAE.

摘要

Recombinant DNA fragment (I) contains the promoter (P) of the Saccharomyces cerevisiae gene YNL279W which regulates transcription of functionally linked structural genes. Independent claims are also included for the following: (1) DNA vector that contains (I); (2) recombinant S. cerevisiae that contains (I); (3) method for identifying activators (A) or inhibitors (B) of G protein-coupled receptors (GPCR); (4) method for producing heterologous proteins (II) in S. cerevisiae by expressing a structural gene for (II) under control of (I); and (5) method for identifying constitutively active mutants of GPCR.
