GSK-3 (glycogen synthase kinase 3)

GSK-3, or glycogen synthase kinase 3, is an enzyme that plays a key role in regulating various cellular processes, including cell growth, metabolism, and gene expression. It functions by adding phosphate groups to specific proteins, which can alter their activity or stability. GSK-3 is involved in pathways that control how cells respond to signals like insulin and growth factors. Because of its central role, it influences health and disease, including conditions like diabetes, Alzheimer's disease, and cancer. Understanding GSK-3 helps researchers develop targeted therapies for these diseases.
