Since the cloning of the BRCA1 and BRCA2 genes less than 10 years ago, a great deal of effort has been expended in attempting to uncover the functions of the encoded proteins. BRCA1 and BRCA2 have now been linked to a wide variety of cellular functions through binding or colocalization with other proteins. In this chapter we focus on the best characterized of these potential functions, DNA repair.
