Glycogen Synthase Kinase-3 Beta (GSK3β), a multifunctional serine/threonine kinase, plays a central role in cellular signaling pathways and autophagy regulation, processes critical to neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease, Huntington’s disease and Amyotrophic Lateral Sclerosis (ALS). The gene discussed is GSK3B; the disease is neurodegenerative disease.
