Eukaryotic cells have evolved an intricate system to resolveDNAdamage to prevent its transmission to daugh-ter cells. This system, collectively knownas theDNAdamage response (DDR) network, includesmany proteinsthat detectDNAdamage, promote repair, andcoordinateprogression through thecell cycle. Becausedefects inthis network can lead to cancer, this network constitutes a barrier against tumorigenesis. Themodular BRCA1carboxyl-terminal (BRCT) domain is frequently present in proteins involved in the DDR, can exist either as anindividual domain or as tandem domains (tBRCT), and can bind phosphorylated peptides. We performed a sys-tematicanalysisofprotein-protein interactions involvingtBRCTin theDDRbycombining literaturecuration,yeasttwo-hybrid screens, and tandem affinity purification coupled to mass spectrometry. We identified 23 proteinscontainingconservedBRCTdomainsandgeneratedahumanprotein-protein interactionnetwork for sevenpro-teinswith tBRCT. This studyalso revealedpreviously unknowncomponents inDNAdamagesignaling, suchasCOMMD1andthe targetof rapamycincomplexmTORC2.Additionally, integrationof tBRCTdomain interactionswith DDR phosphoprotein studies and analysis of kinase-substrate interactions revealed signaling subnet-works that may aid in understanding the involvement of tBRCT in disease and DNA repair.
INTRODUCTION
Cells are constantly subjected toDNAdamage from external aswell as internalcauses. The chemical and physical changes associated with DNA damagecompromise the faithful transmission of genetic information to daughter cells,and thus, cells have evolved an intricate system to coordinate damage sensing,signal transduction, repair processes, and cell cycle progression (1). Defects intheDNAdamage response (DDR)causedbygermlineor somatic changeshaveimportant implications for disease, and the DDR has been proposed to consti-tute an early barrier to tumorigenesis (2, 3). Current cancer therapy regimensexploit weaknesses in this system to selectively kill cancer cells (4, 5). Thus, theestablishment of a platform for the identification of potential sensitizers of ther-apy should accelerate the development of new treatment strategies.
Transmission of intracellular signals often relies on the coordinated in-teractions between protein modular domains and linear peptide motifs (6).A large number of modular domains, defined as units of ~100 amino acidsthat can independently fold in isolation, have been identified, and several ofthem, such as the Src homology 2 (SH2) domain and the BRCA1 C-terminal(BRCT) domain, recognize phosphorylated linear motifs (7–11). The orches-trated recognition of linear motifs by 14-3-3 proteins, proteins with the BRCTdomain, and proteins with the forkhead-associated (FHA) domain is at the coreof DNA damage signaling (12). Modular domains that recognize phosphoryl-ated linear motifs are components of three-part signaling toolkits that also in-
clude protein kinases and phosphatases (10). Thus, to achieve a systemsview of the DDR, it is important to understand not only which modulardomains, linear motifs, kinases, and phosphatases participate in conveyingDNA damage signals but also how their dynamic interactions orchestratethe response.
BRCT domains were initially recognized in the C-terminal region ofBRCA1, a protein encoded by the major breast and ovarian susceptibilitygene with pleiotropic roles in DNA damage repair (13). BRCT domainsare present in a large superfamily of ~40 nonorthologous proteins that partic-ipate in cell cycle checkpoints and in the DDR (14, 15). BRCT domains areversatile modules that mediate protein-protein and protein nucleic acid inter-actions (16). Several BRCT domains recognize linear motifs phosphorylatedby kinases that are activated by DNA damage (8, 9, 17). Therefore, proteinsfound to interact with BRCT domains are likely to have roles in the cellularresponse to DNA damage.
To gain further insight into the determinants of DDR signal transduction,we generated a human protein-protein interaction network (PIN) centered oninteractions mediated by the BRCT domain. This network contains kinases,phosphatases, and other potential BRCT targets previously unknown to par-ticipate in the DDR. In addition, bioinformatics analysis of the constituents ofthe network enabled the identification of biological processes and proteincomplexes that integrate the DDR with other cellular activities, such as cellcycle regulation and transcription. This interaction network has implicationsfor cancer therapy for which understanding the cellular response to DDR-inducing chemotherapy and radiation therapy can be used to improve pa-tient survival and quality of life during treatment.

(Fig. 1A and table S1). Of those, only DBF4B had not been previouslyrecognized as encoding a BRCT-containing protein. Because DBF4Bhas some, but not all, of the structural hallmarks of BRCT domains, finaldetermination of the classification of this protein as a BRCT-containingone requires structural and functional confirmation. We also identifieda group of eight genes that encode proteins with truncated or degener-ated (lacking conserved residues or structural motifs) BRCT domains(Fig. 1A and table S1). BRCT-encoding geneswere located scattered along different au-tosomal chromosomes; none was located insex chromosomes (table S1). Several of thegenes encode for BRCT domain–containingproteins involved in DNAmetabolism, such asDNA polymerases and polymerase-associatedproteins (encoded by POLL, POLM, REV1,RFC1, and DNTT) and DNA ligases (en-coded by LIG4 and LIG3). Unlike some othermodular domains that preferentially co-occur with other specific modules, BRCTdomains co-occurred with many differentdomains (Fig. 1A).
BRCT in tandem: A differentclass of BRCT domainsBRCT domains in several proteins recog-nize and bind phosphorylated serine residues(phosphoserines) (8, 9). BRCT domainsfound in tandem (Fig. 1A) can behave as asingle structural unit (18, 19) that binds phos-phopeptides through recognition pocketsformed by both BRCT units (20–23). Thestructural basis for phosphopeptide recogni-tion by single BRCTs is presently unknown(9, 24). Therefore, we propose that these tan-dem BRCT (tBRCT) domains represent adistinct class of BRCT domains. An un-rooted tree for all of the individual humanBRCTunits revealed that they group in sev-eral distinct branches (Fig. 1B, top). Toexplore the relationship between tBRCTdomains, we generated an unrooted treein which the units were not the individualBRCTs but rather the tBRCT domains (de-fined as two singleton BRCTs connectedby a linker region) (Fig. 1B, bottom). Thetwo singletons from a tandem frequentlyoriginated from different branches of theunrooted BRCT singleton tree (Fig. 1B).Indeed, only in the tandem domains forTP53BP1 did the two singletons come fromthe same branch. Thus, we hypothesize thatthe sequence asymmetry arising from tBRCTdomain composed of BRCT singletons withdifferent evolutionary origins reflects the struc-tural determinants for phosphopeptide rec-ognition and specificity (20–23).
To probe the biology of tBRCT domains,we generated a comprehensive PIN centeredon tBRCT domain–mediated interactions.We focused our search on proteins for which
there was structural or functional evidence in the literature that the tBRCTfunctioned as a single unit (Materials and Methods). Because these do-mains might display phosphorylation-independent modes of binding,we did not initially restrict the analysis to phosphorylation-dependentinteractions. Our final list contained seven tBRCT domains from ECT2,LIG4, MDC1, BARD1, TP53BP1, BRCA1, and the C-terminal tandemfrom PAXIP1.

Fig. 1. The BRCT superfamily. (A) Depiction of the minimal complement of all human proteins containingBRCT domains. Individual diagrams represent the predominant splice forms in the published literaturewith the number of amino acid residues in parentheses. BRCT domains (blue boxes) are illustrated withother co-occurring domains. Proteins at the bottom left (dashed line box) represent those with truncated ordegenerated BRCT domains (tan boxes). The proteins are drawn to scale. (B) Human sequences for theisolated BRCT domains were used to cluster singleton and tBRCT domains on the basis of sequencealignments using the neighbor-joining method to generate unrooted trees. Top (BRCT singletons): Un-rooted tree illustrating amino acid sequence conservation between individual BRCT singleton domains withbootstrapping scores represented by lowercase letters (see key for percent support). Numbers shown afterunderscore in protein names refer to BRCT relative position (for example, TOPBP1_57 refers to the fifth BRCTin TOPBP1, which contains seven BRCTs, starting from the N terminus). Bottom (BRCT tandems): Unrootedtree illustrating amino acid sequence conservation between tBRCT domains. Numbers shown afterunderscore in protein names refer to tBRCT’s relative position (for example, PAXIP1_t3 refers to the thirdtBRCT in PAXIP1). Colored bars below protein names represent the position of the individual BRCT domainsin different branches from the BRCT singleton tree above.
