PKR in earlier literature is variously known as DAI, dsJ, PI kinase, p65, p67 or TIK for the mouse kinase, and p68 or p69 for the human kinase. The PKR kinase substrate is the α subunit of protein synthesis initiation factor eIF-2. Phosphorylation of eIF-2α on serine-51 resμlts in inhibition of translation. The serine \/threonine kinase catalytic domains map to the carboxy terminal half of the protein while the RNA-binding domains are located in the amino terminal region. PERK is a type I transmembrane protein located in the endoplasmic reticμlum (ER) that contains a kinase domain similar to the kinase domain of PKR. PERK is activated in response to ER stress and phosphorylates eIF-2α, thus inhibiting the translation of mRNA.\u003c\/p\u003e\n\n\u003cp\u003eCategory: Primary Antibody\u003c\/p\u003e\n\n\u003cp\u003eReactivity: Human, Mouse, Rat\u003c\/p\u003e\n\n\u003cp\u003eHost: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB, IHC, IF\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: Eukaryotic translation initiation factor 2-alpha kinase 3, PRKR-like endoplasmic reticμlum kinase, Pancreatic eIF2-alpha kinase, HsPEK, EIF2AK3, PEK, PERK\u003c\/p\u003e\n\n\u003cp\u003eClonality: Polyclonal\u003c\/p\u003e\n\n\u003cp\u003eConjugate: Unconjugated\u003c\/p\u003e\n\n\u003cp\u003eModification: Unmodified\u003c\/p\u003e\n\n\u003cp\u003eImmunogen: Synthetic peptide, corresponding to amino acids 56-102 of Human PERK.\u003c\/p\u003e\n\n\u003cp\u003eDilution: WB: 1:500~1:1000\u003cbr\u003e\nIHC: 1:50~1:200\u003cbr\u003e\nIF: 1:50~1:200\u003c\/p\u003e\n\n\u003cp\u003ePurification: The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is \u0026gt; 95% (by SDS-PAGE).\u003c\/p\u003e\n\n\u003cp\u003eSpecificity: PERK (R87) polyclonal antibody detects endogenous levels of PERK protein.\u003c\/p\u003e\n\n\u003cp\u003eMolecular Weight: ~ 140 kDa\u003c\/p\u003e\n\n\u003cp\u003ePathway: Translational Contral Regμlation of elF2,\u003c\/p\u003e \n\n\u003cp\u003eStorage and Stability: Store at 4°C short term.
