The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 (EIF2aK3). Standards or samples are then added to the appropriate microtiter plate wells with a biotin-conjugated antibody specific to Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 (EIF2aK3). Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 (EIF2aK3), biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Eukaryotic Translation Initiation Factor 2 Alpha Kinase 3 (EIF2aK3) in the samples is then determined by comparing the O.D. of the samples to the standard curve.

NCBI Description

The protein encoded by this gene 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. It is a type I membrane protein located in the endoplasmic reticulum (ER), where it is induced by ER stress caused by malfolded proteins. Mutations in this gene are associated with Wolcott-Rallison syndrome. [provided by RefSeq, Jan 2010]

Uniprot Description

PERK: a transmembrane protein kinase of the PEK family resident in the endoplasmic reticulum (ER) membrane and is linked to insulin processing. Couples ER stress to translation inhibition. Stress induces autophosphorylation of its kinase domain and increases its activity. Phosphorylates the alpha subunit of eukaryotic translation-initiation factor 2 (eIF2alpha), leading to its inactivation and thus to a rapid reduction of translational initiation and repression of global protein synthesis. A critical effector of unfolded protein response (UPR)-induced G1 growth arrest due to the loss of cyclin d1. Forms dimers with BiP in resting cells. Oligomerizes in ER-stressed cells. LOF mutations cause Wolcott-Rallison syndrome (WRS), characterized by insulin-dependent diabetes in early infancy and, later, multiple system abnormalities. Neuronal death in Alzheimer?s and Parkinson?s diseases is thought to be due to ER stress and has been weakly linked to PEK.
