URP signaling in this organelle is activated by the stress-induced sequestering of the protein (*) BiP, and the heterotrimeric protein Sec61 is a doughnut-shaped translocon located in the membrane of this organelle.
One process in this organelle is inhibited by the transfer of a certain compound onto dolichol phosphate in the mechanism of action of the drug Tunicamycin. A common method of studying this organelle begins by fragmenting cells in solution, centrifuging the solution, and then examining the resultant "microsomes" on a sucrose gradient. URP signaling in this organelle is activated by the stress-induced sequestering of the protein (*) BiP, and the heterotrimeric protein Sec61 is a doughnut-shaped translocon located in the membrane of this organelle. In eukaryotes, signal recognition particle functions explicitly to target proteins to this organelle, and proteins with a KDEL motif will be returned by retrograde transport to this organelle from the Golgi Body. For 10 points, name this organelle whose "rough" variety is distinguished by the presence of ribosomes.
