Synthesis pass · prose summary of the discoveries below

ABRAXAS2 (ABRO1/KIAA0157/FAM175B) is a cytoplasmic scaffold protein that defines the BRISC deubiquitinase complex and directs Lys63-linked deubiquitination across innate immune, hematopoietic, telomeric, and cardiac contexts (PMID:20656690, PMID:20656689). It binds BRCC36 directly, and the minimal BRCC36-ABRO1 heterodimer retains K63-specific DUB activity; selectivity arises from the orientation of the substrate isopeptide bond in the active site rather than preferential chain binding (PMID:20032457). Structural work established that ABRO1 contacts switch BRCC36 into an active conformation, and that a higher-order 'super-dimer' (dimer of heterodimers) is required for catalysis and for engagement of targeting proteins such as SHMT2 and RAP80, with SHMT2 binding by ABRO1 acting as an inhibitory brake on chain cleavage (PMID:26344097, PMID:31253574). ABRO1 confers cytoplasmic localization to BRCC36, in contrast to the paralog Abraxas, which assembles the nuclear BRCA1-A complex; both complexes share BRE and NBA1/MERIT40, and loss of BRISC shifts the balance toward nuclear BRCA1-A activity at DNA double-strand breaks (PMID:20656690, PMID:20656689, PMID:21282113). Through this scaffolded DUB activity, BRISC/ABRO1 removes K63 chains from defined substrates: tankyrase 1 to control sister telomere resolution (PMID:27993934), JAK2 downstream of the LNK SH2 domain to restrain HSC expansion and thrombopoietin signaling (PMID:30755420), NLRP3 to license inflammasome activation in macrophages (PMID:37781816), PPM1B in a YAP-dependent phase-separated condensate during vascular stiffening (PMID:39742393), and β-catenin at K508 to limit its nuclear accumulation and prevent cardiac hypertrophy (PMID:41789465). Independently of its DUB scaffolding role, ABRO1 protects stalled and reversed replication forks from DNA2/WRN-mediated degradation, and its loss drives chromosome instability, cytosolic ssDNA accumulation, and cGAS-STING activation (PMID:28860160, PMID:35817959). ABRO1 also stabilizes p53 via USP7 and stabilizes BRCC3 itself by competing with the E3 ligase WWP2, while its own levels are subject to transcriptional control by YY1 and to pathogen-driven degradation by the bacterial effector NleG6 through TOLLIP-mediated autophagy (PMID:25283148, PMID:33107021, PMID:32845162, PMID:40013521).

2010 ABRAXAS2 (KIAA0157/ABRO1) is a cytoplasmic scaffold protein that forms a distinct complex with BRCC36 (separate from the nuclear BRCA1-A complex). KIAA0157 localizes mainly in the cytosol and activates BRCC36 DUB activity in the cytoplasm. Reduction of KIAA0157 expression led to an increase of the BRCA1-A complex in the nucleus, indicating fine balance between the two complexes in vivo. Co-immunoprecipitation, subcellular fractionation, siRNA knockdown, functional DUB assays The Journal of biological chemistry High 20656690
2010 Within the BRISC complex, KIAA0157 (ABRO1/ABRAXAS2) is the only interaction required for BRCC36 DUB activity; BRISC deficiency enhanced formation of the BRCA1-RAP80 complex in vivo, increasing BRCA1 levels at DNA double-strand breaks. In vitro DUB activity assays with purified complexes, Co-IP, siRNA knockdown, laser-induced DSB recruitment assays The Journal of biological chemistry High 20656689
2009 ABRO1 binds directly to BRCC36 and the BRCC36-ABRO1 heterodimer constitutes a minimal complex retaining Lys63-specific DUB activity. BRISC selectivity for K63-linked chains is not due to preferential binding to K63 polyubiquitin but is dictated by orientation of the substrate isopeptide bond within the active site. Biochemical reconstitution of heterodimer, in vitro DUB assays with defined ubiquitin substrates, binding studies The Journal of biological chemistry High 20032457
2015 Crystal structure of the active BRCC36-KIAA0157 (ABRAXAS2) heterodimer and an inactive BRCC36 homodimer was solved. KIAA0157 contacts switch BRCC36 to an active conformation. Higher-order 'super-dimer' assembly (dimer of heterodimers) is required for DUB activity and for interaction with targeting proteins SHMT2 and RAP80, implicating super-dimerization as a regulatory mechanism controlling subcellular localization and biological function. X-ray crystallography, in vitro DUB activity assays, mutagenesis, co-immunoprecipitation, size-exclusion chromatography Molecular cell High 26344097
2019 Cryo-EM/crystal structures of BRISC and BRCA1-A complexes revealed that ABRO1 (in BRISC) binds SHMT2α (a metabolic enzyme), and this interaction prevents BRCC36 from binding and cleaving ubiquitin chains, establishing a regulatory inhibitory mechanism. In BRCA1-A, the paralog ABRAXAS integrates RAP80 and sequesters BRCA1 away from DSB sites. The two adaptor subunits confer distinct targeting and regulatory functions to BRCC36.

2011 Both BRCC36-containing complexes (nuclear BRCA1-A with Abraxas; cytoplasmic BRISC with ABRO1) share BRE and NBA1/MERIT40 subunits. NBA1 interacts with BRE through a C-terminal conserved motif of NBA1 and the C-terminal UEV domain of BRE, and this interaction is critical for maintaining the integrity of both complexes and for cellular resistance to ionizing radiation.

2017 ABRO1 protects stalled replication fork stability by inhibiting DNA2 nuclease/WRN helicase-mediated degradation of reversed forks. Depletion of RAD51 prevented DNA2/WRN-dependent fork degradation in Abro1-deficient cells, placing ABRO1 in a fork protection pathway distinct from BRCA2 (which blocks MRE11-dependent degradation).

2022 Abro1 (and FANCD2) protect stalled replication forks, and their deficiency leads to accumulation of cytosolic single-stranded DNA (containing ribosomal DNA) that activates cGAS-STING-dependent innate immune signaling in a DNA2-dependent manner.

2014 ABRO1 stabilizes p53 by facilitating the interaction of p53 with the deubiquitinase USP7.

2012 ABRO1 interacts directly with ATF4, ATF5, and JunD (AP-1 family transcription factors). Under cellular stress, ABRO1 translocates from the cytoplasm to the nucleus and co-localizes with ATF4; this ATF4-ABRO1 interaction is required for the cytoprotective function of ABRO1 following oxidative stress.

2010 ABRO1/KIAA0157 interacts with THAP5, a zinc finger transcription factor involved in G2/M control and apoptosis. ABRO1 protein levels increase in myocardial ischemia/reperfusion injury; reducing ABRO1 exacerbated cardiomyocyte death while overexpression provided protection against oxidative stress-induced apoptosis, linked to decreased Lys63-linked ubiquitination of specific substrates.

2016 ABRO1/BRCC36 (BRISC complex) removes K63-linked ubiquitin chains from tankyrase 1 during G1 phase, countering the action of E3 ligase RNF8 that adds K63-linked chains in late S/G2. This cell cycle-regulated ubiquitination/deubiquitination controls tankyrase 1 stabilization, its association with telomeres, and timely sister telomere resolution.

2019 The LNK SH2 domain directly interacts with a phosphorylated tyrosine residue in KIAA0157 (ABRAXAS2). KIAA0157 deficiency in mice leads to expansion of phenotypic and functional HSCs. BRISC (via KIAA0157) attenuates TPO-induced JAK2 K63-ubiquitination; BRISC depletion increases JAK2 K63-ubiquitination, JAK2 activation, MPL receptor surface levels, and membrane-proximal JAK2/MPL association.
