Polyclonal

KLH conjugated Synthesised phosphopeptide: human PKR around the phosphorylation site of Thr446

Human

EIF2AK2

Interferon-induced, double-stranded RNA-activated protein kinase

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.
