sentences:  A study found that Nbs1 is the most diverged in DNA sequence in the MRN complex between different primate species and that there is a high degree of species specificity, causing variability in promotion of the HSV-1 life cycle.The same study found that Nbs1 interacts with HSV-1's ICP0 proteins in an area of structural disorder of the nibrin.This suggests that in general, viruses commonly interact in intrinsically disordered domains in host proteins.
