WebNov 10, 2024 · Phosphorylation is the predominant PTM regulating FOXO activity and is mediated by several kinases, which are classified into FOXO-inactivating kinases, such as AKT, SGK 58, ERK 59, p38 (refs 60,... WebApr 1, 2024 · The PI3K-AKT pathway has been shown to negatively regulate FOXO3 by phosphorylation, which results in the nuclear export of FOXO3 [10, 11]. Notably, phosphorylated AKT was detected in all FOXO3 ...
WebGrowth-factor initiated kinase‑mediated phosphorylation of FOXOs promotes their interaction with the 14-3-3 protein, leading to export from the nucleus to the cytoplasm; this provides an example of the phenomena of nuclear exclusion in cell biology. FOXOs are also regulated by ubiqutin proteasome pathways.
