Type: Specificity Subtype: Motif hiding | |||||||
| Motif hiding occurs when there is a large difference in intrinsic affinity of overlapping or adjacent motifs for their respective binding partners, or a large difference in the local abundance of these partners. Binding of an effector to one motif sterically masks the overlapping or adjacent motif, thereby precluding it from binding. Binding of the masking molecule can be PTM-dependent or -independent. | |||||||
| ADA22_HUMAN | LIG_14-3-3_3 | 831 854 | 836 859 | Phosphorylation-induced binding of dimeric 14-3-3 protein beta/alpha (YWHAB) to Disintegrin and metalloproteinase domain-containing protein 22 (ADAM22) blocks ER retention motifs in Disintegrin and metalloproteinase domain-containing protein 22 (ADAM22) and regulates transport of this protein to the membrane. | |||

| GPR15_HUMAN | LIG_14-3-3_4 | 356 | 360 | Phosphorylation-induced binding of 14-3-3 protein beta/alpha (YWHAB) promotes cell surface expression of G-protein coupled receptor 15 (GPR15) by releasing the receptor from the ER retrieval/retention pathway that is mediated by the interaction of its ER retention motif with Coatomer subunit beta (COPB1). | |||

| HG2A_HUMAN | LIG_14-3-3_3 | 5 | 10 | The basic ER retention motif of HLA class II histocompatibility antigen gamma chain (CD74) is blocked from binding to Coatomer subunit beta (COPB1) by phosphorylation-induced binding of 14-3-3 protein beta/alpha (YWHAB), regulating its release from the ER and trafficking to the plasma membrane. | |||
| HG2A_HUMAN | TRG_ER_diArg_1 | 3 | 5 | The basic ER retention motif of HLA class II histocompatibility antigen gamma chain (CD74) is blocked from binding to Coatomer subunit beta (COPB1) by phosphorylation-induced binding of 14-3-3 protein beta/alpha (YWHAB), regulating its release from the ER and trafficking to the plasma membrane. | |||
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. | |||||||
| MPIP3_HUMAN | LIG_14-3-3_3 | 213 | 218 | Phosphorylation of S216 in a 14-3-3-binding motif of M-phase inducer phosphatase 3 (CDC25C) by Serine/threonine-protein kinase Chk1 (CHEK1) induces binding to 14-3-3 protein beta/alpha (YWHAB), which negatively regulates M-phase inducer phosphatase 3 (CDC25C). | |||
| BAD_RAT | LIG_14-3-3_1 | 134 | 139 | Phosphorylation of S137 by RAC-alpha serine/threonine-protein kinase (Akt1) in the 14-3-3-binding motif of Bcl2 antagonist of cell death (Bad) induces binding to the 14-3-3 protein beta/alpha (YWHAB) protein. This interaction inhibits the pro-apoptotic activity of Bcl2 antagonist of cell death (Bad). | |||
| HDAC4_HUMAN | LIG_14-3-3_3 | 629 | 634 | Phosphorylation of S632 in the 14-3-3-binding motif of Histone deacetylase 4 (HDAC4) induces binding to the 14-3-3 protein beta/alpha (YWHAB) protein. This interaction sequesters Histone deacetylase 4 (HDAC4) in the cytoplasm, thereby inhibiting their transcription repression activity. | |||
| MPIP2_HUMAN | LIG_14-3-3_3 | 320 | 325 | Phosphorylation of S321 in the 14-3-3-binding motif of M-phase inducer phosphatase 2 (CDC25B) by Cyclin-dependent kinase 1 (CDK1) during mitosis abolishes binding of the motif, phosphorylated at S323, to 14-3-3 protein beta/alpha (YWHAB), thereby maintaining active Cdc25B. | |||
