CC -!- FUNCTION: Component of the BRCA1-A complex, a complex that specifically
CC recognizes 'Lys-63'-linked ubiquitinated histones H2A and H2AX at DNA
CC lesions sites, leading to target the BRCA1-BARD1 heterodimer to sites
CC of DNA damage at double-strand breaks (DSBs). The BRCA1-A complex also
CC possesses deubiquitinase activity that specifically removes 'Lys-63'-
CC linked ubiquitin on histones H2A and H2AX. In the BRCA1-A complex, it
CC is required for the complex integrity and its localization at DSBs.
CC Component of the BRISC complex, a multiprotein complex that
CC specifically cleaves 'Lys-63'-linked ubiquitin in various substrates.
CC In these 2 complexes, it is probably required to maintain the stability
CC of BABAM2 and help the 'Lys-63'-linked deubiquitinase activity mediated
CC by BRCC3/BRCC36 component. The BRISC complex is required for normal
CC mitotic spindle assembly and microtubule attachment to kinetochores via
CC its role in deubiquitinating NUMA1. Plays a role in interferon
CC signaling via its role in the deubiquitination of the interferon
CC receptor IFNAR1; deubiquitination increases IFNAR1 activity by
CC enhancing its stability and cell surface expression. Down-regulates the
CC response to bacterial lipopolysaccharide (LPS) via its role in IFNAR1
CC deubiquitination. {ECO:0000250|UniProtKB:Q9NWV8}.
CC -!- SUBUNIT: Component of the ARISC complex, at least composed of
CC UIMC1/RAP80, ABRAXAS1, BRCC3/BRCC36, BABAM2 and BABAM1/NBA1. Component
CC of the BRCA1-A complex, at least composed of BRCA1, BARD1, UIMC1/RAP80,
CC ABRAXAS1, BRCC3/BRCC36, BABAM2 and BABAM1/NBA1. In the BRCA1-A complex,
CC interacts directly with ABRAXAS1 and BABAM2. Component of the BRISC
CC complex, at least composed of ABRAXAS2, BRCC3/BRCC36, BABAM2 and
CC BABAM1/NBA1. Identified in a complex with SHMT2 and the other subunits
CC of the BRISC complex. {ECO:0000250|UniProtKB:Q9NWV8}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9NWV8}. Nucleus
CC {ECO:0000250|UniProtKB:Q9NWV8}. Note=Localizes at sites of DNA damage
CC at double-strand breaks (DSBs). {ECO:0000250|UniProtKB:Q9NWV8}.
CC -!- DOMAIN: The VWFA-like region is similar to the VWFA domain. Its
CC presence reveals similarities between the structure of the 19S
CC proteasome and the BRCA1-A complexes. {ECO:0000250|UniProtKB:Q9NWV8}.
CC -!- SIMILARITY: Belongs to the BABAM1 family. {ECO:0000305}.
