Second (C-terminal) BRCT domain in X-ray repair cross-complementing protein 1 (XRCC1) and similar proteins; XRCC1 is a DNA repair protein that corrects defective DNA strand-break repair and sister chromatid exchange following treatment with ionizing radiation and alkylating agents. It forms homodimers and interacts with polynucleotide kinase (PNK), DNA polymerase-beta (POLB), DNA ligase III (LIG3), APTX, APLF, and APEX1. XRCC1 contains an N-terminal XRCC1-specific domain and two BRCT domains. This model corresponds to the second BRCT domain.

BRCT domain, a BRCA1 C-terminus domain; This BRCT domain, a BRCA1 C-terminus region, is found on many RAP1 proteins, usually at the very N-terminus. The function in human at least of a BRCT is to contribute to the heterogeneity of the telomere DNA length, but that may not be its general function, which remains unknown.

317-388 1.44e-15

BRCA1 C Terminus (BRCT) domain; The BRCT domain is found predominantly in proteins involved in cell cycle checkpoint functions responsive to DNA damage. The BRCT domain of XRCC1 forms a homodimer in the crystal structure. This suggests that pairs of BRCT domains associate as homo- or heterodimers. BRCT domains are often found as tandem-repeat pairs. Structures of the BRCA1 BRCT domains revealed a basis for a widely utilized head-to-tail BRCT-BRCT oligomerization mode. This conserved tandem BRCT architecture facilitates formation of the canonical BRCT phospho-peptide interaction cleft at a groove between the BRCT domains. Disease associated missense and nonsense mutations in the BRCA1 BRCT domains disrupt peptide binding by directly occluding this peptide binding groove, or by disrupting key conserved BRCT core folding determinants.

Structures of the BRCA1 BRCT domains revealed a basis for a widely utilized head-to-tail BRCT-BRCT oligomerization mode. This conserved tandem BRCT architecture facilitates formation of the canonical BRCT phospho-peptide interaction cleft at a groove between the BRCT domains. Disease associated missense and nonsense mutations in the BRCA1 BRCT domains disrupt peptide binding by directly occluding this peptide binding groove, or by disrupting key conserved BRCT core folding determinants.

C-terminal domain of the breast cancer suppressor protein (BRCA1) and related domains; The BRCT (BRCA1 C-terminus) domain is found within many DNA damage repair and cell cycle checkpoint proteins. BRCT domains interact with each other forming homo/hetero BRCT multimers, but are also involved in BRCT-non-BRCT interactions and interactions within DNA strand breaks. BRCT tandem repeats bind to phosphopeptides; it has been shown that the repeats in human BRCA1 bind specifically to pS-X-X-F motifs, mediating the interaction between BRCA1 and the DNA helicase BACH1, or BRCA1 and CtIP, a transcriptional corepressor. It is assumed that BRCT repeats play similar roles in many signaling pathways associated with the response to DNA damage.

322-384 5.38e-05

BRCT domain of nibrin and similar proteins; Nibrin (NBN), also termed Nijmegen breakage syndrome protein 1 (NBS1), or cell cycle regulatory protein p95, is a novel DNA double-strand break repair protein that is mutated in Nijmegen breakage syndrome. It is a component of the MRE11-RAD50-NBN (MRN complex) which plays a critical role in the cellular response to DNA damage and the maintenance of chromosome integrity. The BRCT (Breast Cancer Suppressor Protein BRCA1, carboxy-terminal) domain is found within many DNA damage repair and cell cycle checkpoint proteins. The unique diversity of this domain superfamily allows BRCT modules to interact forming homo/hetero BRCT multimers, BRCT-non-BRCT interactions, and interactions within DNA strand breaks. The Trp-X-X-X-Cys/Ser signature motif of the BRCT family is absent in this group.

second BRCT domain of Schizosaccharomyces pombe BRCT-containing protein 1 (BRC1) and similar proteins; Schizosaccharomyces pombe BRC1 is required for mitotic fidelity, specifically in the G2 phase of the cell cycle. It plays a role in chromatin organization. The family also includes Cryptococcus neoformans DNA ligase 4 (LIG4, also known as DNA ligase IV or polydeoxyribonucleotide synthase [ATP] 4), which is involved in dsDNA break repair, and plays a role in non-homologous integration (NHI) pathways where it is required in the final step of non-homologus end-joining. Members in this family contains six BRCT domains. This family corresponds to the second repeat.

C-terminal domain of the breast cancer suppressor protein (BRCA1) and related domains; The BRCT (BRCA1 C-terminus) domain is found within many DNA damage repair and cell cycle checkpoint proteins. BRCT domains interact with each other forming homo/hetero BRCT multimers, but are also involved in BRCT-non-BRCT interactions and interactions within DNA strand breaks. BRCT tandem repeats bind to phosphopeptides; it has been shown that the repeats in human BRCA1 bind specifically to pS-X-X-F motifs, mediating the interaction between BRCA1 and the DNA helicase BACH1, or BRCA1 and CtIP, a transcriptional corepressor. It is assumed that BRCT repeats play similar roles in many signaling pathways associated with the response to DNA damage.
