MMS21

NSE2, PSO10, SUMO ligase MMS21, L000001125, YEL019C
SUMO ligase and component of the SMC5-SMC6 complex; this complex plays a key role in the removal of X-shaped DNA structures that arise between sister chromatids during DNA replication and repair; required for efficient sister chromatid cohesion; mutants are sensitive to methyl methanesulfonate and show increased spontaneous mutation and mitotic recombination; SUMOylates and inhibits Snf1p function

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.

Publication

The Smc5/6 complex counteracts R-loop formation at highly transcribed genes in cooperation with RNase H2.

Roy S, Adhikary H, Isler S, D'Amours D

The R-loop is a common transcriptional by-product that consists of an RNA-DNA duplex joined to a displaced strand of genomic DNA. While the effects of R-loops on health and disease are well established, there is still an incomplete understanding of the cellular processes responsible for their removal from eukaryotic genomes. Here, we show that a core regulator of chromosome architecture ... [more]

Ontology Terms

Additional Notes

  • Loss of Smc5/6 complex E3-ligase activity in the mms21-H202Y mutant also gave rise to a synthetic growth defect when combined with RNase H mutations
