The field of FA was both excited as well as surprised when the first cloned genes encoded proteins that resembled no known protein motif. Several binding proteins were described, yet no biochemical function could be discerned. Now, 11 years after the cloning of FANCC, we have in hand 8 FA genes, and the FA field has turned 180? from one dealing with orphan proteins to one well-ensconced in the mainstream of cancer biology: the FANCD1 and FANCD2 proteins are BRCA2 and a BRCA1 interactor, respectively. We now have the ability to assess FA function in the context of the biochemistry of these proteins, which are the subject of intense focus. In addition, we now have a potential mechanism for the modification of FANCD2: FANCL, the latest FA gene to be cloned, may be the ubiquitin ligase responsible for the monoubiquitination of FANCD2. This would represent the first biochemical mechanism established in the FA pathway response to DNA damage.
