SLX8

SUMO-targeted ubiquitin ligase complex subunit SLX8, YER116C
Subunit of Slx5-Slx8 SUMO-targeted ubiquitin ligase (STUbL) complex; stimulated by prior attachment of SUMO to the substrate; contains a C-terminal RING domain; forms nuclear foci upon DNA replication stress; null mutants are aneuploid, have a metaphase delay, and spindle defects including: mispositioned spindles, fish hook spindles, and aberrant spindle kinetics; required for maintenance of genome integrity like human ortholog RNF4

Protein group modification and synergy in the SUMO pathway as exemplified in DNA repair.

Psakhye I, Jentsch S

Protein modification by SUMO affects a wide range of protein substrates. Surprisingly, although SUMO pathway mutants display strong phenotypes, the function of individual SUMO modifications is often enigmatic, and SUMOylation-defective mutants commonly lack notable phenotypes. Here, we use DNA double-strand break repair as an example and show that DNA damage triggers a SUMOylation wave, leading to simultaneous multisite modifications of ... [more]
