GSK3 Signaling

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.


GSK3 (Glycogen Synthase Kinase-3) is a ubiquitously expressed, highly conserved serine/threonine protein kinase found in all eukaryotes. Identified originally as a regulator of glycogen metabolism, GSK3 acts as a downstream regulatory switch for numerous signaling pathways, including cellular responses to WNT, Growth Factors, Insulin, RTK (Receptor Tyrosine Kinases), Hedgehog pathways, and GPCR (G-Protein-Coupled Receptors) and is involved in a wide range of signal transduction cascades involving cellular processes, ranging from glycogen metabolism, cell development, gene transcription, protein translation to cytoskeletal organization, cell cycle regulation, proliferation and apoptosis. Unlike most protein kinases involved in signaling, GSK3 is active in unstimulated, resting cells and its activity is diminished during cellular responses. Another peculiarity compared with other protein kinases is its preference for [...]
