The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 - 2 µg/ml.
Use at an assay dependent concentration. Predicted molecular weight: 47 kDa. Application note: reducing conditions.
Use at an assay dependent concentration.
FunctionComponent of the BRCA1-A complex, a complex that specifically recognizes '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. In the BRCA1-A complex, it acts as a central scaffold protein that assembles the various components of the BRCA1-A complex and mediates the recruitment of BRCA1.
Sequence similaritiesBelongs to the FAM175 family. Abraxas subfamily.
DomainThe MPN-like region is similar to the MPN (JAB/Mov34) domain. Its presence reveals similarities between the structure of the 19S proteasome and the BRCA1-A complexes.
Post-translational modificationsPhosphorylation of Ser-406 of the pSXXF motif by ATM or ATR constitutes a specific recognition motif for the BRCT domain of BRCA1. Phosphorylated upon DNA damage, probably by ATM or ATR.
Cellular localizationNucleus. Localizes at sites of DNA damage at double-strand breaks.
