Ultraviolet-damaged DNA binding protein (UV-DDB) is an important factor involved in DNA repair. To study the role of UV-DDB, we attempted to obtain the cDNA and the protein of a plant UV-DDB. We succeeded in isolating both genes for UV-DDB subunits from rice (Oryza sativa cv. Nipponbare), designated as OsUV-DDB1 and OsUV-DDB2. OsUV-DDB2 (65 kDa) was much larger than human UV-DDB2, but immunoprecipitation and gel mobility shift assay suggested that OsUV-DDB2 is a plant counterpart of UV-DDB2. The transcripts were expressed in proliferating tissues such as the meristem, but were detected at only low levels in the mature leaves, although the leaves are strongly exposed to UV. These transcripts were induced in the meristem after UV-irradiation. The expression levels of OsUV-DDB were significantly reduced when cell proliferation was temporarily halted. These results indicated that the level of OsUV-DDB expression is correlated with cell proliferation, and its expression may be required mostly for DNA repair in DNA replication.
