Protein Structure

Function |
Ubiquitin-binding protein that specifically recognizes and binds 'Lys-63'-linked ubiquitin. Plays a central role in the BRCA1-A complex by specifically binding 'Lys-63'-linked ubiquitinated histones H2A and H2AX at DNA lesions sites, leading to target the BRCA1-BARD1 heterodimer to sites of DNA damage at double-strand breaks (DSBs). The BRCA1-A complex also possesses deubiquitinase activity that specifically removes 'Lys-63'-linked ubiquitin on histones H2A and H2AX. Also weakly binds monoubiquitin but with much less affinity than 'Lys-63'-linked ubiquitin. May interact with monoubiquitinated histones H2A and H2B; the relevance of such results is however unclear in vivo. Does not bind Lys-48'-linked ubiquitin. May indirectly act as a transcriptional repressor by inhibiting the interaction of NR6A1 with the corepressor NCOR1. {ECO:0000269PubMed:12080054, ECO:0000269PubMed:17525340, ECO:0000269PubMed:17525341, ECO:0000269PubMed:17525342, ECO:0000269PubMed:17621610, ECO:0000269PubMed:17643121, ECO:0000269PubMed:19015238, ECO:0000269PubMed:19202061, ECO:0000269PubMed:19261748}.
