FOXO3a regulation by Akt. Growth factors/hormone stimulate PI3k phosphorylation of Akt, FOXO3a is phosphorylated by Akt, 14-3-3 also binds FOXO3a DNA binding sites, further preventing its activity in the nucleus. It is then tagged for degradation via ubiquitination and then degraded in a proteasome. Adapted from (Wilson, 2009 [49]).
