Eif2Ak3 Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 plays an important role in the study of neurodegenerative diseases. This page provides comprehensive information about this topic, including its mechanisms, significance in disease processes, and therapeutic implications.
Introduction
Eif2Ak3 Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
EIF2AK3 (also known as PERK or EIF2AK1) is an ER transmembrane kinase that initiates the integrated stress response (ISR). It phosphorylates eIF2α to reduce protein translation during ER stress[@harding2000].
In the brain, EIF2AK3 is expressed in neurons and glia, with activation in response to ER stress.
