It has been shown that the 104 N-terminal amino acids of the maize streak virus coat protein bind DNA non- specifically [1]. This family also includes various geminivirus movement proteins that are nuclear export factors or shuttles. One member BR1 facilitates the export of both ds and ss DNA form the nucleus [3].
