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.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-PERK C-terminal specifically recognizes PERK.


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) 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.
