Abstract
FANCB protein is a component of the Fanconi Anemia (FA) core complex needed for DNA repair. Within the core complex, FANCB forms a protein subcomplex with two other proteins, FAAP100, and an E3 RING ligase FANCL (BL100) to monoubiquitinate FANCD2 and FANCI (ID2), a process that is defective in 95% of all FA patients. FA is a rare, genetic cancer pre-disposition syndrome characterized by chromosomal instability and hypersensitivity to DNA crosslinking agents, such as those used in chemotherapy like mitomycin C (MMC) (Kennedy D'Andrea, 2006). FANCB is the only known X-linked FA gene, and mutations account for 1% of FA cases (Alter Rosenberg, 2013).
