Our Abpromise guarantee covers the use of ab134798 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use at an assay dependent concentration. Predicted molecular weight: 80 kDa. Preliminary experiments gave an approx 60 kDa band in Human Heart and Spleen lysates and in lysates of cell lines A431, HeLa and HepG2 after 0.3 ug/ml antibody staining. Please note that currently we cannot find an explanation in the literature for the band we observe given the calculated size of 79.7 kDa according to NP_057374.3. The 60 kDa band was successfully blocked by incubation with the immunizing peptide.
IHC-P Use a concentration of 3.75 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.


  • 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.
