General description

Protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK)/EIF2AK3 (eukaryotic translation initiation factor 2 α kinase 3) is a type I transmembrane protein, located on ER (endoplasmic reticulum). It is a member of the eIF2α kinase subfamily. This gene is located on human chromosome 2p. EIF2AK3 has 16 exons and is made of cytoplasmic and kinase domains.

Specificity

The antibody detects endogenous levels of PEK/PERK only when phosphorylated at threonine 981.

Immunogen

Peptide sequence around phosphorylation site of threonine 981(A-R-H(p)-T-G) derived from Human PEK/PERK.

Biochem/physiol Actions

Protein kinase R (PKR)-like endoplasmic reticulum kinase (PERK) helps to detect the protein-folding imbalance created by endoplasmic reticulum (ER) stress. EIF2AK3 works as an endoplasmic reticulum (ER) stress sensor to modulate global protein synthesis. Mutation in EIF2AK3 gene results in Wolcott-rallison syndrome.

Features and Benefits

Evaluate our antibodies with complete peace of mind. If the antibody does not perform in your application, we will issue a full credit or replacement antibody. Learn more.

Physical form

Rabbit IgG in phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
