Application
Anti-PERK (C-terminal) antibody produced in rabbit has been used for western blotting and ERK (extracellular-signal-regulated kinase) phosphorylation assays.
Biochem/physiol Actions
Protein kinase RNA-like endoplasmic reticulum kinase (PERK)responds to distinct cellular stress signals.
Protein kinase RNA-like endoplasmic reticulum kinase (PERK) is an endoplasmic reticulum (ER) stress sensor which phosphorylates eukaryotic initiation factor 2 α (eIF2α), thereby reducing the translation of most messenger RNAs (mRNAs). In mice models of frontotemporal dementia, the suppression of translation in a PERK-eIF2α-dependent manner plays a key role in neuronal loss. PERK confers protection to heart against pressure overload-induced congestive heart failure. Mutations in this gene are linked with Wolcott-Rallison syndrome (WRS) which is characterized by permanent neonatal diabetes, exocrine-deficient pancreas, growth retardation and osteopenia.

General description
Protein kinase RNA-like endoplasmic reticulum kinase (PERK) is one of the three mammalian unfolded protein response (UPR) transducers. It is a highly conserved eukaryotic initiation factor 2 α (eIF2α) kinase. The gene encoding this protein is localized on human chromosome 2p11.2.
Protein kinase RNA-like endoplasmic reticulum kinase (PERK)belongs to a family of eukaryotic initiation factor 2 α (eIF2α)kinases. It is a transmembrane kinase that is highly expressed in the pancreas. PERK contains two main domains: a kinase domain and an N-terminal domain like inositol- requiring enzyme-1 (IRE1), a protein involved in the unfolded protein response (UPR).
Immunogen

Physical form
Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.
Specificity
Anti-PERK C-terminal specifically recognizes PERK.
