Eukaryotischer Translations-Initiation-Factor 2-alpha-Kinase 3

Das vom EIF2AK3-Gen kodierte Enzym ist in der Lage die Translation einer jeden Eukarioten Zelle durch Phosphorilierung zu stoppen. Dies hat insbesondere eine wichtige Kontrollfunktion, wenn sich durch chemischen oder physikaischen Stress fehlgefaltete Proteine bilden. Mutationen führen zur autosomal rezessiven Erkrankung Wolcott-Rallison-Syndrom.
