Mammalian P58 IPK is an inhibitor of PERK [180] which is induced at a later phase of ER stress ... because of mutations or unbalanced ratios of subunits of hetero-oligomeric pro- teins, unfolded or misfolded proteins accumulate in the ER in an event called ER stress.

Because deletion of P58 IPK increases the amount of phosphorylated eIF2a in the cell [58], it is thought to function as a feedback regulator of translation in the later phase of ER stress.
