ChIP Use a concentration of 4 µg/ml.
IHC-P 1/200. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.

See protocols (link:

WB 1/1000. Detects a band of approximately 68 kDa (predicted molecular weight: 62 kDa).Can be blocked with PKR (phospho T446) peptide (ab181660).
IP 1/10.
  • 追加情報Is unsuitable for Flow Cyt or ICC/IF.
  • ターゲット情報

    • 機能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.
    • 配列類似性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.
    • 翻訳後修飾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.
