Switch #: SWTI000663

Switch type: Binary

Switch subtype: Physicochemical compatibility

Description:
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.

Participants:
(1) E3 SUMO-protein ligase PIAS1 (PIAS1)
(2) Small ubiquitin-related modifier 1 (SUMO1)

(1) An Acetylation Switch Regulates SUMO-Dependent Protein Interaction Networks.
