PPP1R15A (Protein Phosphatase 1 Regulatory Subunit 15A), also known as GADD34 (Growth Arrest and DNA Damage-inducible protein 34), is a stress-responsive regulatory subunit of protein phosphatase 1 (PP1). It plays a critical role in cellular stress recovery pathways, particularly during the unfolded protein response (UPR) in the endoplasmic reticulum (ER). Under ER stress, PPP1R15A is upregulated and forms a complex with PP1 to dephosphorylate eukaryotic translation initiation factor 2α (eIF2α), restoring global protein synthesis and promoting cell survival. Dysregulation of PPP1R15A has been implicated in neurodegenerative diseases, cancer, and metabolic disorders.
Antibodies targeting PPP1R15A are essential tools for studying its expression, localization, and function in stress response mechanisms. These antibodies are typically developed in hosts like rabbits or mice using immunogenic peptides or recombinant protein fragments. They enable detection via techniques such as Western blotting, immunofluorescence, and immunohistochemistry. Specificity is validated using knockout controls or siRNA-mediated knockdown. Commercially available PPP1R15A antibodies often target conserved regions, such as the C-terminal domain (aa 500-636 in humans), and are used to investigate its interaction with PP1. stress granule dynamics, or therapeutic targeting in diseases like Alzheimer’s or diabetes. Proper validation ensures reliability in distinguishing PPP1R15A isoforms and avoiding cross-reactivity with homologous proteins like PPP1R15B (CReP).
