PERK / TRP channels
Name: Eukaryotic translation initiation factor 2-alpha kinase 3
(PERK)
Official Symbol: EIF2AK3
provided by HGNC
Function:
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) (By similarity).
