PIK3CA Antibody

PIK3CA Antibody is a rabbit polyclonal antibody directed against PIK3CA, offered by Assay Genie for research applications. Reported applications include WB. Reported reactivity: Mouse. Purified by Peptide Affinity.

PIK3CA encodes the catalytic subunit p110α of phosphoinositide 3-kinase (PI3K), a central component of the PI3K/AKT/mTOR signaling pathway. This pathway is essential for regulating cell growth, metabolism, survival, and synaptic plasticity in the nervous system. While PIK3CA is well-characterized in oncology, its emerging role in neurodegenerative disease is gaining increasing attention. In neurons, PIK3CA activity supports axonal growth, dendritic arborization, and resistance to oxidative stress. Dysregulation of PI3K signaling—whether through genetic mutations, altered expression, or upstream receptor dysfunction—can impair neuronal survival and contribute to synaptic degeneration. In Alzheimer’s disease, reduced PI3K/AKT signaling is associated with increased tau phosphorylation, amyloid-beta toxicity, and impaired autophagy. Conversely, hyperactivation of this pathway has been linked to aberrant protein synthesis and neurodevelopmental disorders. PIK3CA also modulates neuroinflammatory responses by influencing microglial activation and cytokine production. Its role in maintaining blood-brain barrier integrity and regulating neuronal-glial interactions further underscores its relevance in neurodegenerative pathology. Therapeutic strategies targeting PIK3CA and its downstream effectors are being explored to restore cellular homeostasis, enhance neuroprotection, and slow disease progression. As a master regulator of neuronal resilience, PIK3CA represents a promising biomarker and intervention point in the treatment of neurodegenerative diseases. This antibody is also available conjugated to ATTO 390, ATTO 488, ATTO 594, APC, Biotin, FITC, HRP, PerCP and RPE. Supplied in 100 µg.
