研究背景

功能:

Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 (eIF-2-alpha/EIF2S1) on 'Ser-52' during the unfolded protein response (UPR) and in response to low amino acid availability. Converts phosphorylated eIF-2-alpha/EIF2S1 either in a global protein synthesis inhibitor, leading to a reduced overall utilization of amino acids, or to a translation initiation activator of specific mRNAs, such as the transcriptional activator ATF4, and hence allowing ATF4-mediated reprogramming of amino acid biosynthetic gene expression to alleviate nutrient depletion. Serves as a critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin-D1 (CCND1). Involved in control of mitochondrial morphology and function.

翻译修饰:

Oligomerization of the N-terminal ER luminal domain by ER stress promotes PERK trans-autophosphorylation of the C-terminal cytoplasmic kinase domain at multiple residues including Thr-982 on the kinase activation loop (By similarity). Autophosphorylated. Phosphorylated at Tyr-619 following endoplasmic reticulum stress, leading to activate its tyrosine-protein kinase activity. Dephosphorylated by PTPN1/TP1B, leading to inactivate its enzyme activity.

N-glycosylated.

ADP-ribosylated by PARP16 upon ER stress, which increases kinase activity.

细胞定位:

Endoplasmic reticulum membrane>Single-pass type I membrane protein.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
组织特异性:

Ubiquitous. A high level expression is seen in secretory tissues.

亚基结构:

Forms dimers with HSPA5/BIP in resting cells (By similarity). Oligomerizes in ER-stressed cells (By similarity). Interacts with DNAJC3 and MFN2 (By similarity). Interacts with TMEM33. Interacts with PDIA6.

蛋白家族:

The lumenal domain senses perturbations in protein folding in the ER, probably through reversible interaction with HSPA5/BIP.

Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. GCN2 subfamily.
