title: A role for the internal repeat of the Kaposi's sarcoma-associated herpesvirus latent nuclear antigen in the persistence of an episomal viral genome.
abstract: The latent nuclear antigen (LANA) of Kaposi's sarcoma-associated herpesvirus (KSHV) is required for the replication and partitioning of latent viral genomes. It contains an extended internal repeat (IR) region whose function is only incompletely understood. We constructed KSHV genomes lacking either LANA (KSHV-ΔLANA) or the IR region of LANA (KSHV-LANAΔ329-931). Although still capable of replicating a plasmid containing a latent origin of replication, LANAΔ329-931 does not support the establishment of stable cell lines containing a KSHV genome. These findings suggest a role for the LANA IR in KSHV episomal maintenance without its being required for replication.
