  • Immunohistochemical analysis of paraffin-embedded rat testis tissue using BRCA1 Antibody. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH 6.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody at 1/100 dilution in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background
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 (PubMed:10500182, PubMed:12887909, PubMed:12890688, PubMed:14976165, PubMed:16818604, PubMed:17525340, PubMed:19261748). It is unclear whether it also mediates the formation of other types of polyubiquitin chains (PubMed:12890688). The BRCA1-BARD1 heterodimer coordinates a diverse range of cellular pathways such as DNA damage repair, ubiquitination and transcriptional regulation to maintain genomic stability (PubMed:12890688, PubMed:14976165, PubMed:20351172). Regulates centrosomal microtubule nucleation (PubMed:18056443). Required for appropriate cell cycle arrests after ionizing irradiation in both the S-phase and the G2 phase of the cell cycle (PubMed:10724175, PubMed:11836499, PubMed:12183412, PubMed:19261748). Required for FANCD2 targeting to sites of DNA damage (PubMed:12887909). Inhibits lipid synthesis by binding to inactive phosphorylated ACACA and preventing its dephosphorylation (PubMed:16326698). 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 (PubMed:19369211). 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 (PubMed:16818604). Acts as a transcriptional activator (PubMed:20160719)
Subcellular Localization：Nucleus; Chromosome; Cytoplasm; Cytoplasm; Cytoplasm
Expression：
Tissue_specificity:Isomer 1 and isomer 3 are widely expressed. Isomer 3 is expressed at reduced or absent levels in several breast cancer and ovarian cancer cell lines.
Isoforms & Post-Translational Modification：P38398 has 8 isomers: P38398-1: 207721 Da (predicted); P38398-2: 7177 Da (predicted); P38398-3: 85001 Da (predicted); P38398-4: 205838 Da (predicted); P38398-5: 80590 Da (predicted); P38398-6: 78165 Da (predicted); P38398-7: 210266 Da (predicted); P38398-8: 202342 Da (predicted).
Phosphorylated in response to IR, UV, and various stimuli that cause checkpoint activation, probably by ATM or ATR (PubMed:11114888, PubMed:12183412, PubMed:21144835). Phosphorylation at Ser-988 by CHEK2 regulates mitotic spindle assembly (PubMed:10724175, PubMed:20364141). Phosphorylation by AURKA regulates centrosomal microtubule nucleation (PubMed:18056443);Autoubiquitinated, undergoes 'Lys-6'-linked polyubiquitination. 'Lys-6'-linked polyubiquitination does not promote degradation
Subunit：Heterodimer with BARD1 (PubMed:11573085, PubMed:12890688, PubMed:14976165). 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 (PubMed:10783165). This association could be a dynamic process changing throughout the cell cycle and within subnuclear domains (PubMed:10783165). Component of the BRCA1-A complex, at least composed of BRCA1, BARD1, UIMC1/RAP80, ABRAXAS1, BRCC3/BRCC36, BABAM2 and BABAM1/NBA1 (PubMed:19261746, PubMed:19261748, PubMed:19261749, PubMed:20351172). Interacts (via the BRCT domains) with ABRAXAS1 (phosphorylated form); this is important for recruitment to sites of DNA damage (PubMed:17525340, PubMed:17643121, PubMed:17643122, PubMed:23269703, PubMed:24316840, PubMed:26778126). Can form a heterotetramer with two molecules of ABRAXAS1 (phosphorylated form) (PubMed:26778126). Component of the BRCA1-RBBP8 complex (PubMed:16101277). 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 (PubMed:16818604, PubMed:9811458). Associates with RNA polymerase II holoenzyme (PubMed:9662397). Interacts with SMC1A, NELFB, DCLRE1C, CLSPN (PubMed:11739404, PubMed:11877377, PubMed:15096610, PubMed:15456891). Interacts with CHEK1, CHEK2, BAP1, BRCC3, UBXN1 and PCLAF (PubMed:10724175, PubMed:11836499, PubMed:14636569, PubMed:20351172, PubMed:21673012). Interacts (via BRCT domains) with BRIP1 (phosphorylated form) (PubMed:11301010, PubMed:15133502, PubMed:21473589). Interacts with FANCD2 (ubiquitinated form) (PubMed:11239454). Interacts with H2AX (phosphorylated on 'Ser-140') (PubMed:12419185). Interacts (via the BRCT domains) with ACACA (phosphorylated form); the interaction prevents dephosphorylation of ACACA (PubMed:12360400, PubMed:16326698, PubMed:16698035, PubMed:18452305). Part of a BRCA complex containing BRCA1, BRCA2 and PALB2 (PubMed:19369211). Interacts directly with PALB2; the interaction is essential for its function in HRR (PubMed:19369211, PubMed:28319063). Interacts directly with BRCA2; the interaction occurs only in the presence of PALB2 which serves as the bridging protein (PubMed:19369211). Interacts (via the BRCT domains) with LMO4; the interaction represses the transcriptional activity of BRCA1 (PubMed:11751867). Interacts (via the BRCT domains) with CCAR2 (via N-terminus); the interaction represses the transcriptional activator activity of BRCA1 (PubMed:20160719). Interacts with EXD2 (PubMed:26807646). Interacts (via C-terminus) with DHX9; this interaction is direct and links BRCA1 to the RNA polymerase II holoenzyme (PubMed:9662397). Interacts with DNA helicase ZGRF1; the interaction is increased following DNA damage induction (PubMed:34552057)

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
