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       acts as an adapter that bridges the interaction between BABAM1/NBA1 and
CC       the rest of the complex, thereby being required for the complex
CC       integrity and modulating the E3 ubiquitin ligase activity of the BRCA1-
CC       BARD1 heterodimer. Component of the BRISC complex, a multiprotein
CC       complex that specifically cleaves 'Lys-63'-linked ubiquitin in various
CC       substrates. Within the BRISC complex, acts as an adapter that bridges
CC       the interaction between BABAM1/NBA1 and the rest of the complex,
CC       thereby being required for the complex integrity. The BRISC complex is
CC       required for normal mitotic spindle assembly and microtubule attachment
CC       to kinetochores via its role in deubiquitinating NUMA1. The BRISC
CC       complex plays a role in interferon signaling via its role in the
CC       deubiquitination of the interferon receptor IFNAR1; deubiquitination
CC       increases IFNAR1 activity by enhancing its stability and cell surface
CC       expression. Down-regulates the response to bacterial lipopolysaccharide
CC       (LPS) via its role in IFNAR1 deubiquitination. May play a role in
CC       homeostasis or cellular differentiation in cells of neural, epithelial
CC       and germline origins. May also act as a death receptor-associated anti-
CC       apoptotic protein, which inhibits the mitochondrial apoptotic pathway.
CC       May regulate TNF-alpha signaling through its interactions with
CC       TNFRSF1A; however these effects may be indirect.
CC       {ECO:0000250|UniProtKB:Q9NXR7}.
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, BRCC3/BRCC36 and BABAM1/NBA1. Binds
CC       polyubiquitin. Component of the BRISC complex, at least composed of
CC       ABRAXAS2, BRCC3/BRCC36, BABAM2 and BABAM1/NBA1. Identified in a complex
CC       with SHMT2 and the other subunits of the BRISC complex. Component of
CC       the BRCA1/BRCA2 containing complex (BRCC), which also contains BRCA1,
CC       BRCA2, BARD1, BRCC3/BRCC36 and RAD51. BRCC is a ubiquitin E3 ligase
CC       complex that enhances cellular survival following DNA damage. May
CC       interact with FAS and TNFRSF1A. {ECO:0000250|UniProtKB:Q9NXR7}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9NXR7}. Nucleus
CC       {ECO:0000250|UniProtKB:Q9NXR7}. Note=Localizes at sites of DNA damage
CC       at double-strand breaks (DSBs). {ECO:0000250|UniProtKB:Q9NXR7}.
CC   -!- DOMAIN: Contains 2 ubiquitin-conjugating enzyme family-like (UEV-like)
CC       regions. These regions lack the critical Cys residues required for
CC       ubiquitination but retain the ability to bind ubiquitin.
CC       {ECO:0000250|UniProtKB:Q9NXR7}.
CC   -!- SIMILARITY: Belongs to the BABAM2 family. {ECO:0000255}.
