E3 ubiquitin-protein ligase that specifically mediatesthe formation of 'Lys-6'-linked polyubiquitin chains and plays acentral role in DNA repair by facilitating cellular responses toDNA damage. It is unclear whether it also mediates the formation ofother types of polyubiquitin chains. The E3 ubiquitin-proteinligase activity is required for its tumor suppressor function. TheBRCA1-BARD1 heterodimer coordinates a diverse range of cellularpathways such as DNA damage repair, ubiquitination andtranscriptional regulation to maintain genomic stability. Regulatescentrosomal microtubule nucleation. Required for normal cell cycleprogression from G2 to mitosis. Required for appropriate cell cyclearrests after ionizing irradiation in both the S-phase and the G2phase of the cell cycle. Involved in transcriptional regulation ofP21 in response to DNA damage. Required for FANCD2 targeting tosites of DNA damage. May function as a transcriptional regulator.Inhibits lipid synthesis by binding to inactive phosphorylatedACACA and preventing its dephosphorylation. Contributes tohomologous recombination repair (HRR) via its direct interactionwith PALB2, fine-tunes recombinational repair partly through itsmodulatory role in the PALB2-dependent loading of BRCA2-RAD51repair machinery at DNA breaks. Component of the BRCA1-RBBP8complex which regulates CHEK1 activation and controls cell cycleG2/M checkpoints on DNA damage via BRCA1-mediated ubiquitination ofRBBP8.
