pBT3-STE是一个膜蛋白酵母双杂交质粒。The DUALmembrane system is a yeast-based screening assay to identify and characterize protein-protein interactions between integral membrane proteins,membrane-associated proteins and soluble proteins in their natural setting. When using the DUALmembrane system interactions between full-length integral membrane proteins can be detected in situ at cellular membranes.
