  • 功能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.
  • 组织特异性Ubiquitous. A high level expression is seen in secretory tissues.
  • 疾病相关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.
  • 序列相似性Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily.
    Contains 1 protein kinase domain.
  • 结构域The lumenal domain senses perturbations in protein folding in the ER, probably through reversible interaction with HSPA5/BIP.
  • 翻译后修饰Autophosphorylated.
    N-glycosylated.
  • 细胞定位Endoplasmic reticulum membrane.
  • Information by UniProt
