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. | |||||||
| PIAS1_HUMAN | LIG_SUMO_SBM_1 | 457 | 461 | Phosphorylation of S466 and S467 and S468 in the SUMO-binding motif of E3 SUMO-protein ligase PIAS1 (PIAS1) by CK2 subfamily and CK2 subfamily and CK2 subfamily increases the strength of its interaction with Small ubiquitin-related modifier 1 (SUMO1). | |||
| PIAS1_HUMAN | LIG_SUMO_SBM_1 | 457 | 461 | Acetylation of K37 in Small ubiquitin-related modifier 1 (SUMO1) inhibits binding to E3 SUMO-protein ligase PIAS1 (PIAS1). The acetylation counters SUMO-SIM-dependent transcriptional repression processes. Acetylation is countered by Histone deacetylase family, HD type 1 subfamily. | |||
| PIAS2_HUMAN | LIG_SUMO_SBM_1 | 467 | 471 | Acetylation of K37 in Small ubiquitin-related modifier 1 (SUMO1) inhibits binding to E3 SUMO-protein ligase PIAS2 (PIAS2). The acetylation counters SUMO-SIM-dependent transcriptional repression processes. Acetylation is countered by Histone deacetylase family, HD type 1 subfamily. | |||
| DAXX_HUMAN | LIG_SUMO_SBM_1 | 733 | 740 | Acetylation of K37 in the SUMO1 inhibits binding to the Small ubiquitin-related modifier 1 (SUMO1) protein see switch details. SUMO-modified forms of Protein PML (PML) are essential for the recruitment of DAXX to PML nuclear bodies. The acetylated versions of SUMO1/2 failed to trigger recruitment of DAXX into the nuclear bodies. Acetylation is countered by Histone deacetylase family, HD type 1 subfamily. | |||
Type: Binary Subtype: Pre‑translational | |||||||
| Pre-translational mechanisms such as alternative splicing, alternative promoter-usage and/or RNA editing result in inclusion or removal of exons that contain an entire or partial motif. | |||||||
| PML_HUMAN | LIG_SUMO_SBM_1 | 556 | 566 | Alternative splicing removes the Sumoylation interacting motif (SIM) of Protein PML (PML), abrogating binding to Small ubiquitin-related modifier 1 (SUMO1) in Isoform TRIM19epsilon of Protein PML (PML). Isoforms lacking the SIM were resistant to As2O3-induced PML degradation. | |||
Type: Cumulative Subtype: Rheostatic | |||||||
| Rheostatic switches gradually alter the affinity of a motif for a single binding partner by addition of multiple PTMs that additively contribute to this modulation. Additional modifications can either strengthen or weaken an interaction. | |||||||
| DAXX_HUMAN | LIG_SUMO_SBM_1 | 734 | 740 | Multisite phosphorylation of S737 and S739 in the SUMO-binding motif of Death domain-associated protein 6 (DAXX) by CK2 subfamily and CK2 subfamily increases the strength of the interaction with Small ubiquitin-related modifier 1 (SUMO1). | |||
Type: Uncategorised Subtype: Uncategorised | |||||||
| Switches that have unique regulatory mechanisms. As more instances accumulate these switches may be worthy of a novel switch type | |||||||
| DAXX_HUMAN | LIG_SUMO_SBM_1 | 733 | 740 | Sumoylation of K160 induces binding to the Protein PML (PML) protein. SUMO-modified forms of PML are essential for the recruitment of Death domain-associated protein 6 (DAXX) to PML nuclear bodies. | |||
