Bovine papillomavirus E1 protein can, by itself, efficiently drive multiple rounds of DNA synthesis in vitro
Abstract
Bovine papillomavirus E1 protein was found to be as efficient as the simian virus 40 large T antigen in initiating DNA synthesis in a cell-free system derived from COS1 cells. Multiple rounds of DNA synthesis occur, initiated at the bovine papillomavirus type 1 origin. Therefore, E1 functions in vitro as a lytic virus initiator.
