Osaka, Japan - BRCA1, a protein that is well-known for its role in hereditary breast cancer, is an important part of the cellular system that repairs double-strand DNA breaks. Now, researchers from ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have been studying DNA repair by homologous recombination, where the RecA protein repairs breaks in double-stranded DNA by incorporating a ...

A recent study, undertaken by researchers at the Tokyo Metropolitan University and the Tokyo Metropolitan Institute of Medical Science (both Japan), unravels key steps in the process of homologous ...

This illustration shows proteins and DNA in the process of DNA repair. RecA proteins (gold) cradle a single-stranded DNA (brown) that searches for homology with a DNA template (purple). The template ...

Structure Maintenance of Chromosome (SMC) complexes are central to chromosome segregation, compaction and DNA repair, thereby impacting on gene expression and regulation. SMC family members that ...

Experimentation may be what first comes to mind when one contemplates the process of scientific research, but sometimes the best way to understand a system is to simply observe it in its native state.

A day in the life of DNA can be rough. It gets yanked across a dividing cell, zapped by radiation, and assaulted by chemicals. Luckily, cells have developed a complex set of repair mechanisms to ...

New work shows that neurons and other brain cells use DNA double-strand breaks, often associated with cancer, neurodegeneration and aging, to quickly express genes related to learning and memory.
