Background

Function：Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 (EIF2S1/eIF-2-alpha) in response to various stress, such as unfolded protein response (UPR) (PubMed:10026192, PubMed:10677345, PubMed:11907036, PubMed:12086964, PubMed:25925385, PubMed:31023583). Key effector of the integrated stress response (ISR) to unfolded proteins: EIF2AK3/PERK specifically recognizes and binds misfolded proteins, leading to its activation and EIF2S1/eIF-2-alpha phosphorylation (PubMed:10677345, PubMed:27917829, PubMed:31023583). EIF2S1/eIF-2-alpha phosphorylation in response to stress converts EIF2S1/eIF-2-alpha in a global protein synthesis inhibitor, leading to a global attenuation of cap-dependent translation, while concomitantly initiating the preferential translation of ISR-specific mRNAs, such as the transcriptional activators ATF4 and QRICH1, and hence allowing ATF4- and QRICH1-mediated reprogramming (PubMed:10026192, PubMed:10677345, PubMed:31023583, PubMed:33384352). The EIF2AK3/PERK-mediated unfolded protein response increases mitochondrial oxidative phosphorylation by promoting ATF4-mediated expression of COX7A2L/SCAF1, thereby increasing formation of respiratory chain supercomplexes (PubMed:31023583). In contrast to most subcellular compartments, mitochondria are protected from the EIF2AK3/PERK-mediated unfolded protein response due to EIF2AK3/PERK inhibition by ATAD3A at mitochondria-endoplasmic reticulum contact sites (PubMed:39116259). In addition to EIF2S1/eIF-2-alpha, also phosphorylates NFE2L2/NRF2 in response to stress, promoting release of NFE2L2/NRF2 from the BCR(KEAP1) complex, leading to nuclear accumulation and activation of NFE2L2/NRF2 (By similarity). Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin-D1 (CCND1) (By similarity). Involved in control of mitochondrial morphology and function (By similarity)

Subcellular Localization：Endoplasmic reticulum membrane; Single-pass type I membrane protein

Expression：
Tissue_specificity:It is widely distributed and highly expressed in secretory tissues.

Induction:By endoplasmic reticulum stress

Subunit：Forms dimers with HSPA5/BIP in resting cells (PubMed:11907036). Homotetramerizes in response to endoplasmic reticulum (ER) stress, leading to its activation (PubMed:25925385). Interacts with HSP90B1/GRP94 (PubMed:11907036). Interacts with DNAJC3; inhibiting EIF2AK3/PERK activity (By similarity). Interacts with ATAD3A; ATAD3A and EIF2S1/eIF-2-alpha occupy a common binding site within the cytoplasmic loop of EIF2AK3/PERK, leading to prevent EIF2AK3/PERK association with its substrate EIF2S1/eIF-2-alpha (PubMed:39116259). Interacts with MFN2 (By similarity). Interacts with TMEM33 (PubMed:26268696). Interacts with PDIA6 (PubMed:24508390). Interacts with LACC1 (PubMed:31875558)
