Membrane proteins (MPs) are essential in many cellular functions. To maintain proteostasis, MPs are downregulated via ubiquitination and degradation. Here, we describe an optimized protocol to analyze MP degradation using quantitative western blot and flow cytometry-based approaches. We use the degradation of Ypq1, a vacuole membrane lysine transporter, to demonstrate the protocol, which can be adapted for other organelle MPs and thus provide useful tools to study MP regulation in yeast and other model organisms. For complete details on the use and execution of this protocol, please refer to and. Two complementary protocols for quantifying membrane protein degradation in yeast Measures the decrease of full-length protein by quantitative western blot Quantifies the quenching of GFP fluorescence by flow cytometry Adaptable to other fluorescent protein tags and mammalian cells Membrane proteins (MPs) are essential in many cellular functions.
