Glycogen synthase kinase 3 (GSK-3)

Glycogen synthase kinase 3 (GSK-3) is an enzyme that plays a vital role in regulating various cell functions, including metabolism, growth, and gene expression. It acts by adding phosphate groups to specific proteins, which can turn those proteins on or off. GSK-3 is involved in processes like storing energy as glycogen and controlling cell signaling pathways. Its activity must be carefully balanced; improper regulation is linked to conditions such as diabetes, Alzheimer’s disease, and cancer. Overall, GSK-3 is essential for maintaining normal cell functioning and health.
