During the unfolded protein response, if IRE1 ribonuclease activity excised a 27-nucleotide stretch out of the XBP1 mRNA instead of a 26-nucleotide stretch, how do you predict it would impact the resulting XBP1 protein’s contribution to cell’s response?

What effect would the addition of a lysosome-targeting signal have on the subcellular localization of a protein that is normally cytosolic?

Lysosomes contain powerful hydrolytic enzymes, which are transported there from their site of synthesis in the ER via the Golgi apparatus. Why don’t these enzymes damage the constituents of these organelles?
