Most of the Epstein-Barr virus genome in latently infected cells is
in a standard nucleosomal structure, but the region encompassing oriP and the Epstein-Barr virus-encoded small RNA
(EBER) genes shows a distinctive pattern when digested with
micrococcal nuclease. This pattern corresponds to a previously mapped
nuclear matrix attachment region. Although the EBER genes are adjacent
to oriP, there is only a two- to fourfold effect of
oriP on EBER expression. However, sequences containing a
consensus ATF site upstream of EBER1 are important for EBER1 expression.
