IPR011364 is a Breast cancer type 1 susceptibility protein (BRCA1).
<p>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 [[cite:PUB00014583], [cite:PUB00014584]] are believed to be responsible for 45% of inherited breast cancer and more than 80% of inherited breast and ovarian cancer.</p> <p>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 [[cite:PUB00017952], [cite:PUB00066908]]. 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 [[cite:PUB00014805]].</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
| GO term | Namespace | Name | Definition | Relationships |
|---|---|---|---|---|
| Molecular function | DNA binding | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). | ||
| Molecular function | Ubiquitin-protein transferase activity | Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages. | ||
| Cellular component | Nucleus | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. | ||
| Biological process | DNA repair | The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway. | ||
| Molecular function | Zinc ion binding | Interacting selectively and non-covalently with zinc (Zn) ions. |
