This entity is a specific course-dependent process. This process can constitute the course of ER stress. PERK (EIF2AK3) is a single-pass transmembrane protein located in the Endoplasmic Reticulum (ER) membrane. PERK has an N-terminal luminal domain and a C-terminal cytosolic domain. It is maintained in an inactive state by association of its luminal domain with BiP, a chaperone in the ER. Because BiP also binds unfolded proteins, BiP dissociates from PERK when unfolded proteins exceed chaperone activity in the ER.
