应用 Ab评论 说明
WB 1/500 - 1/1000. Detects a band of approximately 62 kDa (predicted molecular weight: 62 kDa).
ELISA 1/20000.
IHC-P 1/50 - 1/100.


  • 功能Following activation by double-stranded RNA in the presence of ATP, the kinase becomes autophosphorylated and can catalyze the phosphorylation of the translation initiation factor EIF2S1, which leads to an inhibition of the initiation of protein synthesis. Double-stranded RNA is generated during the course of a viral infection.
  • 序列相似性Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily.
    Contains 2 DRBM (double-stranded RNA-binding) domains.
    Contains 1 protein kinase domain.
  • 翻译后修饰Autophosphorylated on several Ser and Thr residues. Autophosphorylation of Thr-451 is dependent on Thr-446 and is stimulated by dsRNA binding and dimerization. Autophosphorylation apparently leads to the activation of the kinase.
