Figure 4From: Ubiquitination of HTLV-I Tax in response to DNA damage regulates nuclear complex formation and nuclear exportLysine residues 280 and 284 are required for UV-induced Tax ubiquitination. Tax was immunoprecipitated from 293 cell lysates that had been transfected with Tax or TaxK7/8R, together with HA-UB. Cells were either mock (-) or UV irradiated (+) and the ubiquitination status of Tax was examined by immunoblot analysis for Tax.Back to article page
