The dual kinase endoribonuclease IRE1 is a master regulator of cell fate decisions in cells experiencing endoplasmic reticulum (ER) stress. In mammalian cells, there are two paralogs of IRE1: IRE1 alpha and IRE1 beta. While IRE1 alpha has been extensively studied, much less is understood about IRE1 beta and its role in signaling. In addition, whether the regulation of IRE1 beta's enzymatic activities varies compared to IRE1 alpha is not known. Here, we show that the RNase domain of IRE1 beta is enzymatically active and capable of cleaving an XBP1 RNA mini-substrate in vitro. Using ATP-competitive inhibitors, we find that, like IRE1 alpha, there is an allosteric relationship between the kinase and RNase domains of IRE1 beta. This allowed us to develop a novel toolset of both paralog specific and dual-IRE1 alpha/beta kinase inhibitors that attenuate RNase activity (KIRAs). Using sequence alignments of IRE1 alpha and IRE1 beta, we propose a model for paralog-selective inhibition through interactions with nonconserved residues that differentiate the ATP-binding pockets of IRE1 alpha and IRE1 beta.
