== Disease ==
[https://www.uniprot.org/uniprot/ABRX1_HUMAN ABRX1_HUMAN] Disease susceptibility is associated with variants affecting the gene represented in this entry.
== Function ==
[https://www.uniprot.org/uniprot/ABRX1_HUMAN ABRX1_HUMAN] Involved in DNA damage response and double-strand break (DSB) repair. Component of the BRCA1-A complex, acting as a central scaffold protein that assembles the various components of the complex and mediates the recruitment of BRCA1. The BRCA1-A complex specifically recognizes 'Lys-63'-linked ubiquitinated histones H2A and H2AX at DNA lesion sites, leading to target the BRCA1-BARD1 heterodimer to sites of DNA damage at DSBs. This complex also possesses deubiquitinase activity that specifically removes 'Lys-63'-linked ubiquitin on histones H2A and H2AX.<ref>PMID:17525340</ref> <ref>PMID:17643121</ref> <ref>PMID:17643122</ref> <ref>PMID:18077395</ref> <ref>PMID:19261748</ref> <ref>PMID:22357538</ref> <ref>PMID:26778126</ref>
