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 [2]. Structures of the BRCA1 BRCT domains revealed a basis for a widely utilised head-to-tail BRCT-BRCT oligomerisation mode [3]. 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 [5].

This entry represents the C-terminal alpha helical bundle domain. The eukaryotic GINS complex is essential for the initiation and elongation phases of DNA replication [1-3]. It consists of four paralogous protein subunits (Sld5, Psf1, Psf2 and Psf3), all of which are included in this family.

This entry represents the GINS/PriA/YqbF domain, which is found in the N-terminal region of the GINS complex protein. The GINS complex is crucial for the establishment of DNA replication forks and replisome progression in eukaryotes. The crystal structure of the human GINS complex reveals a heterotetrameric assembly with a pseudo symmetrical layered structure. The complex consists of two heterodimers that create four subunit-subunit interfaces. The subunit structures of the heterodimers consist of two alternating domains, an alpha-helix-rich (A) domain Pfam:PF05916 and a beta-strand-rich (B) domain (this entry).	Domain
