Gene Gene information from NCBI Gene database.
Entrez ID 9451
Gene name Eukaryotic translation initiation factor 2 alpha kinase 3
Gene symbol EIF2AK3
Synonyms (NCBI Gene)
PEKPERKWRS
Chromosome 2
Chromosome location 2p11.2
Summary The protein encoded by this gene phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2, leading to its inactivation, and thus to a rapid reduction of translational initiation and repression of global protein synthesis. This protei
