It has been previously described that some proteins containing HMG boxes are able to bind more strongly to DNA modified with cis-diamminedichloroplatinum (II) (cisplatin) than to unmodified DNA. In the present study, we analyzed the interaction of cisplatin-modified DNA with the human autoantigen NOR-90 (UBF), a transcription factor that contains several HMG boxes. Using autoantibodies against NOR-90 to perform ELISA and immunoprecipitation, it was confirmed that NOR-90 (UBF) was able to bind cisplatin-modified DNA more avidly than unmodified DNA or trans-diamminedichloroplatinum(II) (transplatin) modified DNA. Moreover, by Southwestern, we observed that the 97 kDalton isoform of NOR-90 (UBF1) was able to bind cisplatin-modified DNA more strongly than the 94 kDalton isoform (UBF2); binding of unmodified DNA or transplatin-modified DNA was not detected with either isoform. Sera containing autoantibodies against NOR-90 did not inhibit, but increased the binding of NOR-90 to cisplatin-modified DNA.
