The Faculty of Biology and Biotechnology, Ruhr University Bochum (RUB) and the Institute for Protein Research, Osaka University (IPR) have concluded a cooperation agreement in October 2017. It is complementary to the existing cooperation between the two universities since 2010.
Nucleic Acids Research Breakthrough article describes the biological role of subtelomeric sequences in chromosome maintenance and chromatin structure.
Research teams led by Dr. Junko Kanoh at Osaka University and by Kunihiro Ohta at the University of Tokyo (Japan), have described a study of the biological function of subtelomeric homologous (SH) sequences (and of subtelomeres more generally) through phenotypic analysis of a Schizosaccharomyces pombe (fission yeast) mutant in which all SH sequences in the genome were deleted.

A group of researchers reports on the structure and function of a novel protein named “Calredoxin”. Calredoxin binds calcium and catalyzes in dependence of its binding, redox reactions, particularly driving the detoxification of harmful oxygen species. The researchers are exploring how this protein functions at the crossroad of calcium- and redox-dependent reactions to promote efficient oxygenic photosynthesis.
A chromosome is composed of structurally and functionally distinct domains. However, the molecular mechanisms underlying the formation of chromatin structure and the function of subtelomeres, the telomere-adjacent regions, remain obscure. Here we report the roles of the conserved centromeric protein Shugoshin 2 (Sgo2) in defining chromatin structure and functions of the subtelomeres in the fission yeast Schizosaccharomyces pombe.

5-Methylcytosine (5mC) is oxidized by ten-eleven translocation (TET) enzymes. This process followed by thymine DNA glycosylase is proposed to be the mechanism for methylcytosine demethylation. 5-Hydroxymethylcytosine (5hmC) is one of the most important key oxidative metabolites in the demethylation process, and therefore, simple and accurate method to determine 5hmC at single base resolution is desired. In the present study, we developed a mild catalytic oxidation of 5-hmC using micelle incarcerated oxidants that enables to determine the position of 5hmC at single base resolution.
