General annotation (Comments)
| Function | 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 is unclear whether it also mediates the formation of other types of polyubiquitin chains. The E3 ubiquitin-protein ligase activity is required for its tumor suppressor function. The BRCA1-BARD1 heterodimer coordinates a diverse range of cellular pathways such as DNA damage repair, ubiquitination and transcriptional regulation to maintain genomic stability. Regulates centrosomal microtubule nucleation. Required for normal cell cycle progression from G2 to mitosis. Required for appropriate cell cycle arrests after ionizing irradiation in both the S-phase and the G2 phase of the cell cycle. Involved in transcriptional regulation of P21 in response to DNA damage. Required for FANCD2 targeting to sites of DNA damage. May function as a transcriptional regulator. Contributes to homologous recombination repair (HRR) via its direct interaction with PALB2, fine-tunes recombinational repair partly through its modulatory role in the PALB2-dependent loading of BRCA2-RAD51 repair machinery at DNA breaks. Component of the BRCA1-RBBP8 complex which regulates CHEK1 activation and controls cell cycle G2/M checkpoints on DNA damage via BRCA1-mediated ubiquitination of RBBP8 By similarity. Inhibits lipid synthesis by binding to inactive phosphorylated ACACA and preventing its dephosphorylation. Ref.8 |
| Pathway | |
| Subunit structure | Heterodimer with BARD1. Part of the BRCA1-associated genome surveillance complex (BASC), which contains BRCA1, MSH2, MSH6, MLH1, ATM, BLM, PMS2 and the MRE11-RAD50-NBN protein (MRN) complex. This association could be a dynamic process changing throughout the cell cycle and within subnuclear domains. Component of the BRCA1-A complex, at least composed of the BRCA1, BARD1, UIMC1, BRCC3, BRE and BABAM1. Interacts (via the BRCT domains) with FAM175A. Interacts (via the BRCT domains) with RBBP8 ('Ser-327' phosphorylated form); the interaction ubiquitinates RBBP8, regulates CHEK1 activation, and involves RBBP8 in BRCA1-dependent G2/M checkpoint control on DNA damage. Associates with RNA polymerase II holoenzyme. Interacts with SMC1A and COBRA1. Interacts (via BRCT domains) with BRIP1 (phosphorylated form). Interacts with FANCD2 (ubiquitinated form). Interacts with BAP1. Interacts with DCLRE1C and CLSPN. Interacts with H2AFX (phosphorylated on 'Ser-140'). Interacts with CHEK1 and CHEK2. Interacts with BRCC3. Interacts with AURKA. Interacts with UBXN1. Part of a trimeric complex containing BRCA1, BRCA2 and PALB2. Interacts directly with PALB2; the interaction is essential for its function in HRR. Interacts directly with BRCA2; the interaction occurs only in the presence of PALB2 which serves as the bridging protein. Interacts (via the BRCT domains) with LMO4; the interaction represses the transcriptional activity of BRCA1. Interacts with KIAA0101/PAF15 By similarity. Interacts (via the BRCT domains) with ACACA (phosphorylated form); the interaction prevents dephosphorylation of ACACA. Ref.8 |
| Subcellular location | Nucleus By similarity. Chromosome. Note: Localizes at sites of DNA damage at double-strand breaks (DSBs); recruitment to DNA damage sites is mediated by the BRCA1-A complex By similarity. Ref.10 Ref.11 |
| Tissue specificity | In the embryo, expressed in otic vesicles at day 9.5. At day 10.5, this expression decreases and high levels are found in the neuroectoderm. At days 11-12.5, high levels in differentiating keratinocytes and whisker pad primordia. At days 14-17, expression also observed in kidney epithelial cells. In the adult, highest levels found in spleen, thymus, lymph nodes, epithelial organs, and alveolar and ductal epithelial cells of the mammary gland. Very low levels in brain, kidney, and skin. No expression in heart, liver or lung. |
| Developmental stage | In the mammary gland, expression increases dramatically during pregnancy. Levels fall during lactation and increase again during post-lactational regression of the mammary gland. |
| Domain | The BRCT domains recognize and bind phosphorylated pSXXF motif on proteins. The interaction with the phosphorylated pSXXF motif of FAM175A/Abraxas, recruits BRCA1 at DNA damage sites By similarity. The RING-type zinc finger domain interacts with BAP1 By similarity. |
| Post-translational modification | Phosphorylated in response to IR, UV, and various stimuli that cause checkpoint activation, probably by ATM or ATR. Phosphorylation at Ser-971 by CHEK2 regulates mitotic spindle assembly By similarity. Autoubiquitinated, undergoes 'Lys-6'-linked polyubiquitination. 'Lys-6'-linked polyubiquitination does not promote degradation By similarity. |
| Sequence similarities | Contains 2 BRCT domains. Contains 1 RING-type zinc finger. |
