Description

This entry consists of the E3 SUMO-protein ligase Nse2 (also known as Mms21).

Nse2 is an E3 SUMO-protein ligase component of the SMC5-SMC6 complex [PMID: 12966087, PMID: 15601841]. Nse2 acts as an E3 ligase targeting several proteins for sumoylation and is required for efficient DNA repair and maintenance of genome stability [PMID: 22921571, PMID: 16055714, PMID: 15738391, PMID: 21550342]. Nse2 and SMC5 may also be required for sister chromatid cohesion during prometaphase and mitotic progression; this role is apparently independent of SMC6 [PMID: 19502785]. Nse2 is necessary for normal cell cycle progression in Arabidopsis, where Nse2 mutation results in abnormal root development [PMID: 19682286].
