The single-end invasion: an asymmetric intermediate at the double-strand break to double-Holliday junction transition of meiotic recombination

Article Abstract:

Research has been conducted on the meiotic recombination intermediate occurring during the double-strand break transition to the double-Holliday junction. The identification of this intermediate has been carried out and the analysis of the single-end invasion structural asymmetry indicate that the two ends of the double-strand break interact with the homologue in the temporal succession via biochemically distinct process.

Mus81-Eme1 are essential components of a Holliday junction resolvase

Article Abstract:

Research has been conducted on the fission yeast protein Mus81 related to the XPF subunit of ERCC1-XPF nucleotide excision repair endonuclease. Results indicate that Mus81 and related protein Eme1 are endonuclease components resolving Holliday junctions into linear duplex products.

Identification of human Rap1: implications for telomere evolution

Article Abstract:

Research has been conducted on the human telomeric protein hRap1. Results indicate that ancestral telomeres contain TRF-like and Rap1 proteins.
