Protein Domain : Breast cancer type 1 susceptibility protein (BRCA1) IPR011364

Type	Family
Description	Breast cancer is a common malignancy, affecting 1 in 8 women. A major contributary factor in disease development lies in a positive family history, a correlation that is striking for early-onset breast cancer. Mutations in the DNA-damage repair protein BRCA1 [ , ] are believed to be responsible for 45% of inherited breast cancer and more than 80% of inherited breast and ovarian cancer.The BRCA1 protein is a E3 ubiquitin-protein ligase that specifically mediates the formation of 'Lys-6'-linked polyubiquitin chains and plays a central role in DNA repair by facilitating cellular responses to DNA damage [ , ]. It contains an N-terminal zinc-finger domain. It also contains a BRCT C-terminal domain, an approximately 100 amino acid tandem repeat, which appears to act as a phospho-protein binding domain [].
Short Name	BRCA1
