[[http://www.uniprot.org/uniprot/POLG_NVN68 POLG_NVN68]] Protein p48 may play a role in viral replication by interacting with host VAPA, a vesicle-associated membrane protein that plays a role in SNARE-mediated vesicle fusion. This interaction may target replication complex to intracellular membranes.<ref>PMID:569187</ref> <ref>PMID:11160659</ref> NTPase presumably plays a role in replication.
