General description

Breast cancer type 1 susceptibility protein (BCRA1; RING finger protein 53) functions as a tumor suppressor. BRCA1 is an important member of the DNA repair pathway. After DNA damage, BRCA1 is phosphorylated on multiple serine residues by the ATR kinase or Chk2, and is localized to lesion sites with PCNA. BRCA1 interacts with a wide range of proteins including Rad50, NBS1, and Mre11, c-Abl tyrosine kinase, and γH2A.X, involved in the detection of damaged DNA and activation of appropriate repair pathways. BRCA1 may also respond to DNA damage by promoting gene expression through association with transcriptional proteins and RNA polymerase II, and may regulate the p53 pathway by this mechanism. Previous studies have indicated that mutations in the BRCA1 gene may contribute to the development of breast and ovarian cancer.
