WebNov 13, 2024 · Aside from inducing transcriptional changes via activation of XBP1s, IRE1 has other functionalities that play a role in stress-responsive signaling following ER stress. One of these additional functions is termed regulated IRE1-dependent decay (RIDD), in which the activated IRE1 RNase degrades a variety of ER-associated mRNAs (Fig. 2 A) (56, 57).
