The PPP1R15B antibody is a crucial tool for studying the PPP1R15B protein (Protein Phosphatase 1 Regulatory Subunit 15B), also known as constitutive repressor of eIF2α phosphorylation (CReP). This protein plays a pivotal role in cellular stress responses, particularly within the integrated stress response (ISR) pathway. PPP1R15B regulates protein synthesis by dephosphorylating eukaryotic translation initiation factor 2α (eIF2α), counteracting the activity of stress-induced kinases like PERK. Its function is essential for restoring translational homeostasis after stress and modulating apoptosis under prolonged endoplasmic reticulum (ER) stress.
Antibodies targeting PPP1R15B enable researchers to investigate its expression, localization, and interactions in models of neurodegenerative diseases, cancer, and metabolic disorders. They are widely used in techniques such as Western blotting, immunofluorescence, and immunoprecipitation. Studies utilizing these antibodies have revealed PPP1R15B's involvement in diseases like Alzheimer’s, where dysregulated eIF2α phosphorylation contributes to pathological protein aggregation, and in cancer, where its suppression may enhance chemosensitivity. Commercial PPP1R15B antibodies are typically validated for specificity across human, mouse, and rat samples, with applications spanning basic research and therapeutic development. Understanding PPP1R15B dynamics through antibody-based assays continues to shed light on cellular stress adaptation mechanisms and potential therapeutic targets.
