Nuclear matrix binding site in the Rad51 recombinase.

It has been shown that the key homologous recombination protein Rad51 accumulates in DNA damage-induced nuclear foci that are attached to the nuclear matrix. In the present communication we attempted to find whether Rad51 contains a functional domain responsible for nuclear matrix binding. By alignments of the sequences encoding nuclear matrix targeting signals of human nuclear matrix binding proteins with the whole length human Rad51sequence a putative nuclear matrix targeting signal was identified.
