APY29 is an inhibitor of IRE1α with IC50 value of 0.28μM [1].

IRE1α is a transmembrane protein in ER. It can be activated when unfolded proteins accumulate in ER. APY29 is found to interact with the ATP-binding site of wild-type IRE1α and activate the kinase activity of IRE1α even without upstream ER stress. APY29 acts as a slight activator and stabilizes IRE1α’s kinase domain in an alternative conformation. It is found to restore the ability of dephosphorylated IRE1α to cleave the substrate XBP1 up to about 60% of the levels of normal IRE1α. Furthermore, APY29 increases the oligomer/monomer ratio of IRE1α and finally displays a decrease of IRE1α trans-autophosphorylation [1].
