Hara K, et al. (2012) Membrane-displayed peptide ligand activates the pheromone response pathway in Saccharomyces cerevisiae. J Biochem 151(5):551-7
Abstract: The budding yeast, Saccharomyces cerevisiae, is an attractive host for studying G protein-coupled receptors (GPCRs). We developed a system in which a peptide ligand specific for GPCR is displayed on yeast plasma membrane. The model system described here is based on yeast plasma membrane display of an analogue of a-factor, which is a peptide ligand for Ste2p, the GPCR that activates the yeast pheromone response pathway. a-Factor analogues, containing linkers of varying lengths and produced in yeast cells, became attached to the cell plasma membrane by linking to the glycosylphosphatidylinositol (GPI)-anchored plasma membrane protein Yps1p. We were able to demonstrate that an optimized a-factor analogue activated the pheromone response pathway in S. cerevisiae, as assessed by a fluorescent reporter assay. Furthermore, it was shown that linker length strongly influenced signalling pathway activation. To our knowledge, this is the first report documenting functional signalling by a plasma membrane-displayed ligand in S. cerevisiae.
