SMC5 (Q8IY18) - Overview - Molecular Target Synopsis


SMC5, Structural maintenance of chromosomes protein 5
UniProt Q8IY18

Also Known as SMC5_HUMAN, SMC5, KIAA0594, SMC5L1

Core component of the SMC5-SMC6 complex, a complex involved in repair of 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. Required for sister chromatid cohesion during prometaphase and mitotic progression; the function seems to be independent of SMC6. SMC5-SMC6 complex may prevent transcription of episomal DNA, such as circular viral DNA genome (PubMed:26983541). Forms a heterodimer with SMC6 (PubMed:11408570). Component of the SMC5-SMC6 complex which consists at least of SMC5, SMC6, NSMCE2, NSMCE1, NSMCE4A or EID3 and NSMCE3 (PubMed:18086888). Interacts with NSMCE2 (PubMed:16055714). Interacts with SLF2; this interaction induces an association of the SLF1-SLF2 complex with the SMC5-SMC6 complex (PubMed:25931565). Interacts with RAD18; this interaction is increased in a SLF1 or SLF2-dependent manner (PubMed:25931565).
