  • Target

    • 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.
    • Tissue specificity
      Expressed in testis, ovary, thymus and heart. Expressed in germ cells of the testis.
    • Sequence similarities
      Belongs to the RAP80 family.
      Contains 2 UIM (ubiquitin-interacting motif) repeats.
    • Domain
      The UIM-linker region between the 2 UIM repeats determines the selectivity for 'Lys-63'-linked ubiquitin. The length of the linker is important. The linker reduces the flexibility between the UIM repeats and promotes high-affinity and linkage-selective interactions.
      The Abraxas-interacting region (AIR) mediates the interaction with FAM175A/Abraxas.
    • Post-translational
      Phosphorylated upon DNA damage by ATM or ATR.
    • Cellular localization
      Nucleus. Localizes at sites of DNA damage at double-strand breaks.
