PAIP2 and cytomegalovirus infection: Thus, MDV1 infection, like HCMV infection appears not to interfere with the global cytoplasmic localization of PABP1 but unlike HCMV, MDV1 does not appear to force the infected cells to increase the supply of PABP1 but may have evolved an alternative strategy that reduces the level of the paip2; the inhibitor of PABP1.
