Eukaryotic Translation Initiation Factor 2-Alpha Kinase 1

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Eukaryotic translation initiation factor 2-alpha kinase 1 (630 aa, ~71 kDa) is encoded by the human EIF2AK1 gene. This protein plays a role in both the inhibition of protein synthesis and serine/threonine phosphorylation.
