According to the text, the RAD51 gene is responsible for producing a protein that is crucial for repairing damaged DNA through homologous recombination. This gene is essential for maintaining the integrity of the human genome and plays a major role in safeguarding cells from DNA damage. It is a homologue of the bacterial RecA protein and is also involved in repairing damage caused by X-rays. Rad51 forms stable filaments and interacts with other proteins to carry out its function effectively. Diseases associated with RAD51 include Fanconi Anemia and Mirror Movements 2.
