產(chǎn)品介紹 PERK is a GCN2 Ser/Thr protein kinase which phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2 (EIF2) leading to its inactivation. This results in a reduction of translational initiation and repression of global protein synthesis. Expression of this Type I membrane protein is ubiquitous at low levels but greatest expression is seen in secretory and endocrine tissues. Defects in EIF2AK3 are the cause of Wolcott-Rallison syndrome (WRS), which is a rare autosomal recessive disorder.

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).

Subunit : Forms dimers with HSPA5/BIP in resting cells. Oligomerizes in ER-stressed cells. Interacts with DNAJC3 (By similarity).

Subcellular Location : Endoplasmic reticulum membrane; Single-pass type I membrane protein.

Post-translational modifications : 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 (By similarity).

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

DISEASE : Wolcott-Rallison syndrome (WRS) [MIM:226980]: A rare autosomal recessive disorder, characterized by permanent neonatal or early infancy insulin-dependent diabetes and, at a later age, epiphyseal dysplasia, osteoporosis, growth retardation and other multisystem manifestations, such as hepatic and renal dysfunctions, mental retardation and cardiovascular abnormalities. Note=The disease is caused by mutations affecting the gene represented in this entry.

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

Contains 1 protein kinase domain.
