Rearranges cellular actin to increase intercellular contacts and thereby promote virus cell-to-cell spreading. Induce the outgrowth of long, branched plasma membrane fronds to create intercellular network for virion traffic. The fronds are actin based and RhoA-dependent (By similarity). Interacts with BMRF2. Plasma membrane remodeling is mediated by the cytoplasmic tail. Belongs to the herpesviridae BDLF2 family.
