ターゲット情報

  • 機能
    Phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2 (EIF2), leading to its inactivation and thus to a rapid reduction of translational initiation and repression of global protein synthesis. Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin D1.
  • 組織特異性
    Ubiquitous. A high level expression is seen in secretory tissues.
  • 関連疾患
    Defects in EIF2AK3 are the cause of Wolcott-Rallison syndrome (WRS) [MIM:226980]; also known as multiple epiphyseal dysplasia with early-onset diabetes mellitus. WRS is a rare autosomal recessive disorder, characterized by permanent neonatal or early infancy insulin-dependent diabetes and, at a later age, epiphyseal dysplasia, osteoporosis, growth retardation and other multisystem manifestations, such as hepatic and renal dysfunctions, mental retardation and cardiovascular abnormalities.
  • 配列類似性
    Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily.
    Contains 1 protein kinase domain.
  • ドメイン
    The lumenal domain senses perturbations in protein folding in the ER, probably through reversible interaction with HSPA5/BIP.
  • 翻訳後修飾
    Autophosphorylated.
    N-glycosylated.
  • 細胞内局在
    Endoplasmic reticulum membrane.

  • Anti-PERK antibody (ab77654) at 1/1000 dilution + 293 cell line lysate at 35 µg

    Predicted band size : 125 kDa
  • IHC-P image of PERK staining on human cortical sections using ab77654 (1:500). The tissue was fixed in formaldehyde and the sections were then subjected to heat mediated antigen retrieval using citric acid and permeabilized using Triton-X. The sections were them blocked using 2% BSA for 2 hour at 20°C. ab77654 was diluted 1:500 and incubated with the sections for 18 hours at 4°C. The secondary antibody used was HRP conjugated Goat polyclonal to Rabbit IgG (1:500)
