  • Western blot analysis was performed on extracts from Hela (lane 1, 20 μg), C6 (lane 2, 20 μg), and 293T (lane 3, 20 μg) using PERK Rabbit mAb.Proteins were transferred to a PVDF membrane and blocked with 5% non - fat milk in TBST at 4°C overnight.The primary antibody (1:1000 dilution) and the loading control antibody (beta-Actin, HY-P83730, 1:5000 dilution) were incubated in 5% non-fat milk in TBST for 1 hour at 37°C.Goat Anti - Rabbit IgG - HRP Secondary Antibody (1:20000 dilution) was then applied for 40 minutes at 37°C.

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)

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.
