tokens: These results further support an important role for CBF2 in mediating EBNA2 transactivation ; they identify the hnRNP protein AUF1 as a major component of CBF2 and are also the first evidence of a cis acting sequence other than a CBF1 binding element that is able to confer responsiveness to EBNA2 .
