Tumour-suppressor protein CtIP N-terminal domain; CtIP is predominantly a nuclear protein that complexes with both BRCA1 and the BRCA1-associated RING domain protein (BARD1). At the protein level, CtIP expression varies with cell cycle progression in a pattern identical to that of BRCA1. Thus, the steady-state levels of CtIP polypeptides, which remain low in resting cells and G1 cycling cells, increase dramatically as Dividing cells traverse the G1/S boundary. CtIP can potentially modulate the functions ascribed to BRCA1 in transcriptional regulation, DNA repair, and/or cell cycle checkpoint control. This N-terminal domain carries a coiled-coil region and is essential for homodimerization of the protein. The C-terminal domain is family pfam08573. : Pssm-ID: 463107 [Multi-domain] Cd Length: 120 Bit Score: 178.32 E-value: 2.48e-52

DNA endonuclease activator SAE2/CtIP C-terminus; SAE2 is a protein involved in repairing meiotic and mitotic double-strand breaks in DNA. It has been shown to negatively regulate DNA damage checkpoint signalling. SAE2 is homologous to the CtIP proteins in mammals and an homologous protein in plants. Crucial sequence motifs that are highly conserved are the CxxC and the RHR motifs in this C-terminal part of the protein. In budding yeast, genetic evidence suggests that the SAE2 protein is essential for the processing of hairpin DNA intermediates and meiotic double-strand breaks by Mre11/Rad50 complexes. SAE2 binds DNA and exhibits endonuclease activity on single-stranded DNA independently of Mre11/Rad50 complexes, but hairpin DNA structures are cleaved cooperatively in the presence of Mre11/Rad50 or Mre11/Rad50/Xrs2. Hairpin structures are not processed at the tip by SAE2 but rather at single-stranded DNA regions adjacent to the hairpin. The catalytic activities of SAE2 are important for its biological functions. Although proteins containing this domain were described as endonucleases, it is now known that they actually function as endonuclease activators. This domain contains highly conserved residues at its 15-residue extreme that are indispensable for MRN (Mre11-Rad50-Nbs1) complex activation, through the stimulation of Mre11 endonuclease activity. : Pssm-ID: 462525 Cd Length: 108 Bit Score: 63.15 E-value: 5.71e-12

chromosome segregation protein SMC, primarily archaeal type; SMC (structural maintenance of chromosomes) proteins bind DNA and act in organizing and segregating chromosomes for partition. SMC proteins are found in bacteria, archaea, and eukaryotes. It is found in a single copy and is homodimeric in prokaryotes, but six paralogs (excluded from this family) are found in eukarotes, where SMC proteins are heterodimeric. This family represents the SMC protein of archaea and a few bacteria (Aquifex, Synechocystis, etc); the SMC of other bacteria is described by TIGR02168. The N- and C-terminal domains of this protein are well conserved, but the central hinge region is skewed in composition and highly divergent.
