FANCD2 (Fanconi anemia group D2 Protein, FACD2, FANCD2, FACD)

The FA proteins lack sequence homologies or motifs that could point to a molecular function. Phosphorylation of FANC(Fanconi anemia complementation group) proteins are thought to be important for the function of the FA pathway. Several FA proteins, including FANCA, FANCC, FANCF, and FANCG, interact in a nuclear complex, and this complex is required for the activation (monoubiquitination) of the downstream FANCD2 protein. When monoubiquitinated, the FANCD2 protein colocalizes with the breast cancer susceptibility protein BRCA1 in DNA damage induced foci. In male meiosis, FANCD2 also colocalizes...
