英文摘要Macroautophagy/autophagy is a conserved catabolic process that recycles cytoplasmic material during low energy conditions. becn1/beclin1 (beclin 1, autophagy related) is an essential protein for function of the class 3 phosphatidylinositol 3-kinase (ptdins3k) complexes that play a key role in autophagy nucleation and elongation. here, we show that amp-activated protein kinase (ampk) regulates autophagy by phosphorylating becn1 at thr388. phosphorylation of becn1 is required for autophagy upon glucose withdrawal. becn1(t388a), a phosphorylation defective mutant, suppresses autophagy through decreasing the interaction between pik3c3 (phosphatidylinositol 3-kinase catalytic subunit type 3) and atg14 (autophagy-related 14). the becn1(t388a) mutant has a higher affinity for bcl2 than its wild-type counterpart; the mutant is more prone to dimer formation. conversely, a becn1 phosphorylation mimic mutant, t388d, has stronger binding to pik3c3 and atg14, and promotes higher autophagy activity than the wild-type control. these findings uncover a novel mechanism of autophagy regulation.
