Original Source: GSK3-TIP60-ULK1 signaling pathway links growth factor deprivation to autophagy.

In metazoans, cells depend on extracellular growth factors for energy homeostasis. We found that glycogen synthase kinase-3 (GSK3), when deinhibited by default in cells deprived of growth factors, activates acetyltransferase TIP60 through phosphorylating TIP60-Ser(86), which directly acetylates and stimulates the protein kinase ULK1, which is required for autophagy. Cells engineered to express TIP60(S86A) that cannot be phosphorylated by GSK3 could not undergo serum deprivation-induced autophagy. An acetyla...
