The figure shows the number of cells that have clusters of IRE1 molecules after those cells are treated with various levels of thapsigargin (Tg), a chemical that can induce ER stress. IRE1 can form these clusters when ER stress is induced and this clustering can cause activation of RNAse activity in IRE1. In this experiment, normal IRE1 was used (IRE1α) that can bind to Sec61, along with a modified version of IRE1 that binds to Sec61 more weakly than normal IRE1 (wIRE1α), and another modified version that binds to Sec61 more strongly than normal IRE1 (sIRE1α). From this figure you can conclude that: Question 18 options: IRE1 binding to Sec61 promotes the formation of IRE1 clumps IRE1 binding to Sec61 prevents the formation of IRE1 clumps co-translational translocation is a key process the golgi aparatus is heavily involved in the unfolded protein response The…ILLUSTRATIONS For each of the given proteins: Draw the final location of the following proteins after being translocated.
