A panoply of functions have been proposed for the BRCA1 cancer susceptibility protein, particularly in the response to DNA damage and in transcriptional regulation. This complexity is now exacerbated by the discovery of a distinct splice variant of BRCA1, BRCA1/IRIS, with a previously uncharacterized function in DNA replication. This has implications for understanding tumorigenesis in BRCA1 mutation carriers.
