Type: Binary Subtype: Physicochemical compatibility | |||||||
PTM of a residue in a motif or in its flanking regions alters the physicochemical and/or structural compatibility of the motif with its binding partner. This can either induce or enhance an interaction, or result in inhibition or even abrogation of an interaction. | |||||||
MT_POVM3 | LIG_14-3-3_1 | 254 | 259 | Phosphorylation of S257 in the 14-3-3-binding motif of Middle T antigen induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein. | |||
ATX1_HUMAN | LIG_14-3-3_1 | 772 | 777 | Phosphorylation of S775 by RAC-alpha serine/threonine-protein kinase (AKT1) in the 14-3-3-binding motif of Ataxin-1 (ATXN1) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein. | |||
M3K5_HUMAN | LIG_14-3-3_1 | 963 | 968 | Phosphorylation of S966 in the 14-3-3-binding motif of Mitogen-activated protein kinase kinase kinase 5 (MAP3K5) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein. This interaction inhibits the pro-apoptotic activity of Mitogen-activated protein kinase kinase kinase 5 (MAP3K5). | |||
FOXO4_HUMAN | LIG_14-3-3_2 | 193 | 199 | 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. | |||
PDE3A_HUMAN | LIG_14-3-3_2 | 424 | 430 | Phosphorylation of S428 by in the 14-3-3-binding motif of cGMP-inhibited 3',5'-cyclic phosphodiesterase A (PDE3A) induces binding to the 14-3-3 protein zeta/delta (YWHAZ) protein. | |||
RAF1_HUMAN | LIG_14-3-3_1 | 256 | 261 | Phosphorylation of S257 in the 14-3-3-binding motif of RAF proto-oncogene serine/threonine-protein kinase (RAF1) abolishes binding of the motif, phosphorylated at S259, to 14-3-3 protein zeta/delta (YWHAZ). | |||
Type: Specificity Subtype: Altered binding specificity | |||||||
The balance of the competition for overlapping or adjacent, mutually exclusive interaction interfaces is tipped in favor of one of the interactors by PTM-dependent modulation of the intrinsic affinity of a binding region. Multiple, successive PTMs allow sequential switching of different binding partners in an ordered manner by step-wise alteration of binding specificity. | |||||||
ITB2_HUMAN | LIG_14-3-3_3 | 755 | 760 | Phosphorylation of T758 in Integrin beta-2 (ITGB2) switches the specificity of ITGB2 from Filamin-A (FLNA) to 14-3-3 proteins (e.g. 14-3-3 protein zeta/delta (YWHAZ)). | |||
ATX1_HUMAN | LIG_14-3-3_1 | 772 | 777 | Phosphorylation of S775 switches binding specificity of Ataxin-1 (ATXN1) from the splicing factor Splicing factor U2AF 65 kDa subunit (U2AF2) to 14-3-3 proteins (e.g. 14-3-3 protein zeta/delta (YWHAZ)). While association with the spliceosome protects ATXN1 from self-association, its phosphorylation-dependent recruitment to 14-3-3 proteins (e.g. YWHAZ) might result in aggregation. |
