Properties
Form Liquid
Concentration Lot Specific
Formulation PBS, pH 7.4
Buffer Formulation Phosphate Buffered Saline
Buffer pH pH 7.4
Format Purified
Purification Purified by Protein G affinity chromatography
Specificity Information
Specificity This antibody recognizes full-length BRCA1, a 220 kD nuclear phosphoprotein, and does not recognize the deltaexon 11 splice variant. In a high proportion of breast and ovarian cancer cell lines, BRCA1 aberrantly mislocates to the cytoplasm. Its usefulness to monitor functional inactivation of BRCA1 in sporadic breast cancers is under active investigation.

Sequence Location Nucleus, Chromosome, Cytoplasm
Biological 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:12890688, PubMed:14976165, PubMed:16818604, PubMed:17525340, PubMed:12887909, PubMed:10500182, 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:12183412, PubMed:11836499, 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 rPubMed:10500182, PubMed:10724175, PubMed:11836499, PubMed:12183412, PubMed:12887909, PubMed:12890688, PubMed:14976165, PubMed:16326698, PubMed:16818604, PubMed:17525340, PubMed:18056443, PubMed:19261748, PubMed:19369211, PubMed:20160719, PubMed:20351172}.
