General annotation (Comments)
| Function | Core component of the SMC5-SMC6 complex, a complex involved in DNA double-strand breaks by homologous recombination. The complex may promote sister chromatid homologous recombination by recruiting the SMC1-SMC3 cohesin complex to double-strand breaks. The complex is required for telomere maintenance via recombination in ALT (alternative lengthening of telomeres) cell lines and mediates sumoylation of shelterin complex (telosome) components which is proposed to lead to shelterin complex disassembly in ALT-associated PML bodies (APBs). Required for recruitment of telomeres to PML nuclear bodies. Ref.10 Ref.11 |
| Subunit structure | Forms a heterodimer with SMC5. Component of the SMC5-SMC6 complex which consists at least of SMC5, SMC6, NSMCE2, NSMCE1, NSMCE4A or EID3 and NDNL2. Ref.12 |
| Subcellular location | Nucleus. Chromosome. Chromosome › telomere. Note: Associates with chromatin. Localizes to PML nuclear bodies in ALT cell lines. Ref.1 Ref.11 Ref.12 |
| Tissue specificity | Widely expressed. Overexpressed in testis. Ref.1 |
| Domain | The flexible hinge domain, which separates the large intramolecular coiled coil regions, allows the heterotypic interaction with the corresponding domain of SMC5, forming a V-shaped heterodimer By similarity. |
| Post-translational modification | Sumoylated by NSMCE2/MMS21. Ref.9 Ref.12 Ubiquitinated. Ref.12 |
| Sequence similarities | Belongs to the SMC family. SMC6 subfamily. |
| Sequence caution | The sequence AAH32675.1 differs from that shown. Reason: Contaminating sequence. Potential poly-A sequence. The sequence BAB15236.1 differs from that shown. Reason: Frameshift at position 718. |
