BRC5 overexpression in cells inhibits the interaction between BRCA2 and HMG20b, whereas BRC4 does not. (a) HeLa TetOn cell clones stably expressing either myc-tagged BRC4 (clone 4.23) or BRC5 (clones 5.10) were induced by doxycycline treatment, and the expression of myc-BRC4 or -BRC5 was analyzed by western blotting with anti-myc antibody. β-Actin was used as a loading control. (b) BRCA2-associated protein complexes were immunoprecipitated from myc-BRC4- or -BRC5-expressing cells using protein A-coupled anti-BRCA2 antibody (αB2-9), and western blotted with anti-HMG20b or anti-RAD51 antibodies, as shown.
