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: Isoform 1 and isoform 3 are widely expressed. Isoform 3 is reduced or absent in several breast 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)丨Autoubiquitinated, undergoes 'Lys-6'-linked polyubiquitination

Subunit：Heterodimer with BARD1 (PubMed:11573085, PubMed:12890688, PubMed:14976165)
