Product Category: Polyclonal Antibodies

Host: Rabbit

Species Reactivity: H

Specificity: This PERK antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 537~566 amino acids from the C-terminal region of human PERK.

Cellular Localisation: Endoplasmic reticulum membrane; Single-pass type I membrane protein

Molecular Weight: 125216

Clone: Polyclonal

Gene Name: EIF2AK3

Gene ID: 9451

Function: Metabolic-stress sensing protein kinase that phosphorylates the alpha subunit of eukaryotic translation initiation factor 2 (EIF2S1/eIF-2-alpha) in response to various stress conditions. Key activator of the integrated stress response (ISR) required for adaptation to various stress, such as unfolded protein response (UPR) and low amino acid availability (By similarity) . EIF2S1/eIF-2-alpha phosphorylation in response to stress converts EIF2S1/eIF-2-alpha in a global protein synthesis inhibitor, leading to a global attenuation of cap-dependent translation, while concomitantly initiating the preferential translation of ISR-specific mRNAs, such as the transcriptional activators ATF4 and QRICH1, and hence allowing ATF4- and QRICH1-mediated reprogramming (PubMed:33384352) . Serves as a critical effector of unfolded protein response (UPR) -induced G1 growth arrest due to the loss of cyclin-D1 (CCND1) . Involved in control of mitochondrial morphology and function (By similarity) .

Summary: Tissue Location: Ubiquitous. A high level expression is seen in secretory tissues

Form: Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein G column, eluted with high and low pH buffers and neutralized immediately, followed by dialysis against PBS.

Storage: Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.

Application: IHC-P

Dilution: IHC-P--1:100~500
