Cdc6-2 protein levels increase following UV irradiation. Western blot using antibodies against S. solfataricus Cdc6-1, Cdc6-2 and Cdc6-3. Cell-free extracts were prepared from samples taken from UV-treated and control cultures at the indicated time points. In agreement with the microarray data, the levels of Cdc6-2 protein show a clear increase after UV irradiation, whereas those of Cdc6-1 and Cdc6-3 are reduced.
