Nse2: Proteins and Enzymes

E3 SUMO-protein ligase component of the SMC5-SMC6 complex, a complex involved in DNA double-strand breaks byhomologous recombination. The complex may promote sister chromatid homologous recombination by recruiting theSMC1-SMC3 cohesin complex to double-strand breaks. Acts as a E3 ligase mediating SUMO attachment to various proteinssuch as SMC6L1 and TRAX, and maybe the cohesin components RAD21 and STAG2. SUMO protein-ligase activity is requiredfor the prevention of DNA damage-induced apoptosis by facilitating DNA repair
