Description
Description
The SMC5/6 protein complex consists of a Structural Maintenance of Chromosomes (SMC) heterodimer and Non-Smc-Element (Nse) proteins. It is important for genome stability and is required for homologous DNA recombination-based processes. The complex contains a SUMO-ligase and a putative ubiquitin-ligase. (Adapted from FBrf0221151 and PMID:19308705).
Notes on Group

The existence of this complex in D.mel is inferred by orthogy and mutations in subunits that effect genome stability. In yeast, the Smc5/6 complex is made up of eight subunits that form three sub-complexes: Smc6-Smc5-Nse2, Nse1-Nse3-Nse4, and Nse5-Nse6. Nse5 and Nse6 have no counterparts in higher eukaryotes (FBrf0221151).

Expression of qjt is heavily weighted to the testis, indicating that this variant may be testis-specific.
