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:10882126, PubMed:11106749, PubMed:11430819, PubMed:11997520, PubMed:14978030, PubMed:16418533, PubMed:17998206, PubMed:21954288, PubMed:23921556, PubMed:9930704). 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:11106749, PubMed:16418533, PubMed:17998206, PubMed:21954288, PubMed:23921556, PubMed:29386355, PubMed:9930704). 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:10882126, PubMed:11106749, PubMed:11430819, PubMed:11997520, PubMed:23921556). 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 (By similarity). 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 (PubMed:14517290, PubMed:14978030). Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin-D1 (CCND1) (PubMed:11035797). Involved in control of mitochondrial morphology and function (PubMed:23921556)

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

Expression：
Tissue_specificity:Ubiquitous (PubMed:9930704) . Highly expressed in mouse pancreas, an organ active in protein secretion (at protein level) (PubMed:11430819) .

Induction:By ER stress

Subunit：Forms dimers with HSPA5/BIP in resting cells (PubMed:21543844). Homotetramerizes in response to endoplasmic reticulum (ER) stress, leading to its activation (PubMed:10854322, PubMed:14978030). Interacts with HSP90B1/GRP94 (By similarity). Interacts with DNAJC3; inhibiting EIF2AK3/PERK activity (PubMed:12446838). 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 (By similarity). Interacts with MFN2 (PubMed:23921556). Interacts with TMEM33 (By similarity). Interacts with PDIA6 (By similarity). Interacts with LACC1 (By similarity)

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
