FANCD2 is a protein that plays a crucial role in DNA repair, particularly in the Fanconi anemia pathway. This pathway is essential for maintaining genomic stability, and defects in its components can lead to a rare genetic disorder called Fanconi anemia. FANCD2 is activated by monoubiquitination, a process where a single ubiquitin molecule is attached to it. This modification is a key step in initiating the DNA repair process. Once monoubiquitinated, FANCD2 translocates to the nucleus and forms nuclear foci, which are discrete structures within the cell nucleus that are believed to be sites of DNA damage and repair. These foci are important for recruiting other DNA repair proteins to the site of damage. FANCD2 also interacts with a variety of other proteins involved in DNA repair, including BRCA1 and BRCA2, which are also implicated in Fanconi anemia and breast cancer susceptibility. The proper functioning of FANCD2 is therefore critical for preventing the accumulation of DNA damage and maintaining the integrity of the genome.
