Abstract:Glycogen synthase kinase 3β (GSK3β) is a serine/threonine kinase that regulates numerous cellular processes such as apoptosis, self‐renewal, growth, and metabolism. GSK3β phosphorylates over 100 substrates ranging from cytosolic to nuclear substrate targets, including c‐myc, a key ongogenic transcription factor, leading to control of c‐myc stability. GSK3β is itself regulated by phosphorylation on S9 by signals such as Akt (activated within the phosphatidylinositol‐3kinase, PI3K, signaling pathway), resulting … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
