The PERK (Protein Kinase R-like ER Kinase) antibody targeting Phospho-Thr982 is a crucial tool for studying the unfolded protein response (UPR) in eukaryotic cells. PERK, encoded by the *EIF2AK3* gene, is a transmembrane serine/threonine kinase located in the endoplasmic reticulum (ER). It acts as a sensor of ER stress, activating pathways to restore proteostasis. Upon ER stress, PERK dimerizes and autophosphorylates at specific residues, including Thr982 in humans (Thr980 in mice), a critical step for its kinase activation. Phosphorylation at this site triggers downstream signaling, primarily through phosphorylation of eIF2α, which attenuates global protein synthesis while promoting selective translation of stress-response genes like ATF4.
The Phospho-Thr982 antibody specifically detects PERK when phosphorylated at this residue, enabling researchers to monitor PERK activation in conditions like hypoxia, nutrient deprivation, or diseases involving ER dysfunction (e.g., neurodegenerative disorders, diabetes, cancer). Validated in applications such as Western blotting, immunofluorescence, and immunohistochemistry, this antibody helps elucidate mechanisms of cellular stress adaptation, drug resistance, or apoptosis. Its specificity for the phosphorylated form distinguishes active PERK from its inactive state, making it essential for studies linking ER stress to pathophysiological outcomes. Proper controls (e.g., phosphatase treatment) are recommended to confirm signal specificity.
