EIF2AK2 assay

Eukaryotic translation initiation factor 2 alpha kinase 2

Synonyms: EIF2AK1, PKR, PPP1R83, “protein phosphatase 1, regulatory subunit 83”, PRKR

Family: Other

EIF2AK2 is the double-stranded-RNA-dependent eIF-2α kinase1. It is activated during a viral infection by the binding of double-stranded RNA to its two conserved binding domains2.

EIF2AK2 kinase assay is run on mobility shift microfluidics platform (Caliper), which provides best in industry quality of data. We routinely run services associated with this kinase including: screening, profiling, dose-response studies and kinetic measurements. Please contact us for more information.
