Condensins are essential protein complexes critical for mitotic chromosome organization. Little is known about the function of condensins during interphase, particularly in mammalian cells. Here we report the interphase-specific interaction between condensin I and the DNA nick-sensor poly(ADP-ribose) polymerase 1 (PARP-1). We show that the association between condensin I, PARP-1, and the base excision repair (BER) factor XRCC1 increases dramatically upon singlestrand break damage (SSB) induction. Damage-specific association of condensin I with the BER factors flap endonuclease 1 (FEN-1) and DNA polymerase δ/ε was also observed, suggesting that condensin I is recruited to interact with BER factors at damage sites. Consistent with this, DNA damage rapidly stimulates the chromatin association of PARP-1, condensin I, and XRCC1. Furthermore, depletion of condensin in vivo compromises SSB but not double-strand break (DSB) repair. Our results identify a SSB-specific response of condensin I through PARP-1 and demonstrate a role for condensin in SSB repair.
