CC -!- FUNCTION: Metalloprotease that specifically cleaves 'Lys-63'-linked
CC polyubiquitin chains. Does not have activity toward 'Lys-48'-linked
CC polyubiquitin chains. Component of the BRCA1-A complex, a complex that
CC specifically recognizes 'Lys-63'-linked ubiquitinated histones H2A and
CC H2AX at DNA lesions sites, leading to target the BRCA1-BARD1
CC heterodimer to sites of DNA damage at double-strand breaks (DSBs). In
CC the BRCA1-A complex, it specifically removes 'Lys-63'-linked ubiquitin
CC on histones H2A and H2AX, antagonizing the RNF8-dependent
CC ubiquitination at double-strand breaks (DSBs). Catalytic subunit of the
CC BRISC complex, a multiprotein complex that specifically cleaves 'Lys-
CC 63'-linked ubiquitin in various substrates. Mediates the specific 'Lys-
CC 63'-specific deubiquitination associated with the COP9 signalosome
CC complex (CSN), via the interaction of the BRISC complex with the CSN
CC complex. The BRISC complex is required for normal mitotic spindle
CC assembly and microtubule attachment to kinetochores via its role in
CC deubiquitinating NUMA1. Plays a role in interferon signaling via its
CC role in the deubiquitination of the interferon receptor IFNAR1;
CC deubiquitination increases IFNAR1 activity by enhancing its stability
CC and cell surface expression. Down-regulates the response to bacterial
CC lipopolysaccharide (LPS) via its role in IFNAR1 deubiquitination (By
CC similarity). Deubiquitinates HDAC1 and PWWP2B leading to their
CC stabilization (By similarity). {ECO:0000250|UniProtKB:P46736,
CC ECO:0000250|UniProtKB:P46737}.

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. In the BRISC complex, interacts directly with
CC ABRAXAS2. Identified in a complex with ABRAXAS2 and NUMA1. The BRISC
CC complex interacts with the CSN complex. Component of the BRCA1/BRCA2
CC containing complex (BRCC), which also contains BRCA1, BRCA2, BARD1,
CC BABAM2 and RAD51. BRCC is a ubiquitin E3 ligase complex that enhances
CC cellular survival following DNA damage. Interacts with BRCA1. Binds
CC polyubiquitin (By similarity). Interacts with PWWP2B (By similarity).
CC Interacts with HDAC1; this interaction is enhanced in the presence of
CC PWWP2B (By similarity). {ECO:0000250|UniProtKB:P46736,
CC ECO:0000250|UniProtKB:P46737}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P46736}. Cytoplasm
CC {ECO:0000250|UniProtKB:P46736}. Cytoplasm, cytoskeleton, spindle pole
CC {ECO:0000250|UniProtKB:P46736}. Note=Localizes at sites of DNA damage
CC at double-strand breaks (DSBs). Interaction with ABRAXAS2 retains BRCC3
CC in the cytoplasm. {ECO:0000250|UniProtKB:P46736}.
CC -!- SIMILARITY: Belongs to the peptidase M67A family. BRCC36 subfamily.
CC {ECO:0000305}.
