technique(s)

activity assay: suitable

UniProt accession no.

Gene Information

human ... EIF2AK3(9451)

General description

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 (CCND1)

Packaging

Also available in 10μg size as catalog # 14-916 and in 250 μg as catalog # 14-916-K.

Quality

Routinely evaluated by phosphorylation of the peptide RSRSRSRSRSRSRSR
