Forkhead box protein O4 - FOXO4 - Homo sapiens
|
| LIG_14-3-3_2 | 193 | 199 | Binary | Physicochemical compatibility | Phosphorylation of S197 by in the 14-3-3-binding motif of Forkhead box protein O4 (FOXO4) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein. | details |
| LIG_14-3-3_1 | 29 | 34 | Avidity‑sensing | | Phosphorylation of two 14-3-3-binding motifs in Foxo4 by PKB induces binding of 14-3-3 dimer. In the nucleus, this blocks binding to DNA, while in the cytoplasm it blocks reimport of Foxo4 into the nucleus by blocking its Nuclear Localisation Signal (NLS). Since binding of 14-3-3 to a single motif occurs with an affinity similar to the affinity of Foxo4 for DNA, multivalent binding of 14-3-3 dimer is required for efficient inhibition of DNA binding. | details |
