Rad51C also known as R51H3, Rad51l2A is a member of the RAD51 family, primarily localized in the nucleus, where Rad51C plays an essential role in the homologous recombination repair pathway responsible for fixing DNA double-strand breaks. This nuclear localization is crucial because Rad51C has direct access to the genomic DNA, facilitating accurate and efficient repair processes that maintain genomic stability and prevent mutations that could lead to cancer. These interactions are essential for orchestrating the homologous recombination machinery, ensuring that DNA breaks are repaired correctly and timely. Additionally, Rad51C collaborates with key proteins like BRCA1 and BRCA2, which are critical for the DNA damage response and repair mechanisms, thereby enhancing the cell′s ability to maintain genomic integrity.
