Structural maintenance of chromosomes protein 6 is a protein that in humans is encoded by the SMC6 gene .[ 5] [ 6]
It is involved in the Alternative lengthening of telomeres cancer mechanism.[ 7]
Role in recombination and meiosis
Smc6 and Smc5 proteins form a heterodimeric ring-like structure and together with other non-SMC elements form the SMC-5/6 complex. In the worm Caenorhabditis elegans this complex interacts with the HIM-6(BLM) helicase to promote meiotic recombination intermediate processing and chromosome maturation.[ 8] The SMC-5/6 complex in mouse oocytes is essential for the formation of segregation competent bivalents during meiosis .[ 9] In the yeast Saccharomyces cerevisiae , SMC6 is necessary for resistance to DNA damage as well as for damage-induced interchromosomal and sister chromatid recombination.[ 10] In humans, a chromosome breakage syndrome characterized by severe lung disease in early childhood is associated with a mutation in a component of the SMC-5/6 complex.[ 11] Patient’s cells display chromosome rearrangements , micronuclei , sensitivity to DNA damage and defective homologous recombination .
