The regulation of homologous recombination by RNF138
EF 2015-16
Résumé
DNA double-strand breaks are breaks in individual chromosomes that can arise as a result of metabolism (breathing oxygen) and from environmental sources. These breaks are commonly repaired by one of two mechanisms termed non-homologous end joining and homologous recombination. These two types of repair differ in a very important way. Non homologous end joining connects two pieces of DNA and does not have mechanisms to preserve the integrity of the DNA sequence. Hence, this can cause rearrangements of genes and chromosomes and loss of genetic material--all of which can contribute to the development of cancer. Homologous recombination preserves the original sequence. As such, the choice of pathways is important. We have found that RNF138 plays a critical role in suppressing the error-prone pathway and promoting the error-free pathway.

Abstract
DNA double-strand breaks are breaks in individual chromosomes that can arise as a result of metabolism (breathing oxygen) and from environmental sources. These breaks are commonly repaired by one of two mechanisms termed non-homologous end joining and homologous recombination. These two types of repair differ in a very important way. Non homologous end joining connects two pieces of DNA and does not have mechanisms to preserve the integrity of the DNA sequence. Hence, this can cause rearrangements of genes and chromosomes and loss of genetic material--all of which can contribute to the development of cancer. Homologous recombination preserves the original sequence. As such, the choice of pathways is important. We have found that RNF138 plays a critical role in suppressing the error-prone pathway and promoting the error-free pathway.
