Anti-BRCA1 (phospho S1423) antibody

타겟 정보

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).
