Following statements are regarding to the FOXO3a protein.

A. In the presence of growth factors, FOXO3a is non phosphorylated and mainly localizes to the nucleus, where it activates transcription of several genes encoding pro-apoptotic proteins.

B. When growth factors are removed from the cells, PKB becomes active and phosphorylates FOXO3a.

C. Phosphorylated FOXO3a binds to cytosolic phosphoserine-binding protein 14-3-3 to bind FOXO3a and thus sequester it in the cytosol.

D. Dephosphorylated FOXO3a binds to cytosolic phosphoserine-binding protein 14-3-3 to bind FOXO3a and thus sequester it in the cytosol.
