BAIT

SLX5

HEX3, ULS2, SUMO-targeted ubiquitin ligase complex subunit SLX5, L000000768, YDL013W
Subunit of the Slx5-Slx8 SUMO-targeted ubiquitin ligase (STUbL) complex; stimulated by SUMO-modified substrates; contains a RING domain and two SIM motifs; forms SUMO-dependent nuclear foci, including DNA repair centers; associates with the centromere; 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
Saccharomyces cerevisiae (S288c)
PREY

RAD52

recombinase RAD52, L000001572, YML032C
Protein that stimulates strand exchange; stimulates strand exchange by facilitating Rad51p binding to single-stranded DNA; anneals complementary single-stranded DNA; involved in the repair of double-strand breaks in DNA during vegetative growth and meiosis and UV induced sister chromatid recombination
Saccharomyces cerevisiae (S288c)

Biochemical Activity (Ubiquitination)

An interaction is inferred from the biochemical effect of one protein upon another, for example, GTP-GDP exchange activity or phosphorylation of a substrate by a kinase. The bait protein executes the activity on the substrate hit protein. A Modification value is recorded for interactions of this type with the possible values Phosphorylation, Ubiquitination, Sumoylation, Dephosphorylation, Methylation, Prenylation, Acetylation, Deubiquitination, Proteolytic Processing, Glucosylation, Nedd(Rub1)ylation, Deacetylation, No Modification, Demethylation.

Publication

The yeast Hex3.Slx8 heterodimer is a ubiquitin ligase stimulated by substrate sumoylation.

Hex3 and Slx8 are Saccharomyces cerevisiae proteins with important functions in DNA damage control and maintenance of genomic stability. Both proteins have RING domains at their C termini. Such domains are common in ubiquitin and ubiquitin-like protein ligases (E3s), but little was known about the molecular functions of either protein. In this study we identified HEX3 as a high-copy suppressor ... [more]
