Publication: “Subtelomeres constitute a safeguard for gene expression and chromosome homeostasis”

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.

Press Release: Calredoxin, a novel protein for promoting efficient photosynthesis

Outline

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.

Shugoshin forms a specialized chromatin domain at subtelomeres that regulates transcription and replication timing.

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.
