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 K33 in Small ubiquitin-related modifier 2 (SUMO2) inhibits binding to E3 SUMO-protein ligase PIAS1 (PIAS1). The acetylation counters SUMO-SIM-dependent transcriptional repression processes. An additional interaction is also possible upon acetylation with the Bromodomain of p300 shown to bind the acetylated version of SUMO2. This does not occur with acetylated SUMO1. Acetylation is countered by Histone deacetylase family, HD type 1 subfamily. | |||
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. |
