Abstract: Unlike mice expressing the wild-type E6 (strain K14E6(WT)), the mice expressing E6(I128T) lacked the ability to alter the radiation-induced block to DNA synthesis and promote the formation of benign skin tumors in conjunction with chemical carcinogens.

Abstract: We generated transgenic mice expressing a mutant of E6, E6(I128T), which is defective for binding at least a subset of the alpha-helix partners, including E6AP, the ubiquitin ligase that mediates E6-dependent degradation of the p53 protein, to determine whether binding of alpha-helix partners plays a role in E6-mediated activities in vivo.
