WebCtIP (CtBP-interacting protein) associates with BRCA1 and the Mre11-Rad50-Nbs1 (MRN) complex and plays an essential role in homologous recombination (HR)-mediated DNA double-stranded break (DSB) repair. It has been described that CtIP forms dimers in mammalian cells, but the biological significance is not clear. WebJun 3, 2008 · CtIP (or Ctp1) is another protein that has recently been linked with MRN (Figure 2C). It is a mammalian tumor suppressor whose presence in the nucleus is limited to the S and G2 phases of the cell cycle.
