5. (9pts) You are studying an ER membrane protein, YFG1 (outlined in yellow), with three transmembrane domains (rectangles A, B & C at the amino acid positions according to the following map, connected by soluble domains (wavy lines): N-term 10 10 Com Amino acid position (not to scale) 30 60 80 140 160 310 ABCI YFG1 alkaline phosphatase To determine how the protein is arranged in the ER membrane, you construct a series of shortened YFG1 proteins that are connected...
