Web4. jan 2024 · PERK can be phosphorylated on several residues, particularly in the context of activating autophosphorylation ( Hetz and Papa, 2024 ; Figure S2 G). However, PERK phosphorylation by AMPK has not been reported and phospho-specific antibodies mapping these potential sites are lacking. Webthe sequence identity is low, and PERK also contains a cytosolic kinase domain that under-goes trans-autophosphorylation in response to ER stress. Unlike Ire1, however, PERK also phosphorylatesthe eukaryotic translation initi-ation factor eIF2a. Phosphorylation of eIF2a results in a reduction of general protein syn-
