Binds to the long stretches of ssDNA of the viral DNA replication intermediates created during the protein-primed mechanism of replication of the viral genome and attaches the viral DNA to the membrane of the infected cells (PubMed:11741949) (PubMed:11169113). Required for the redistribution of replicating viral DNA from the initial replication site to membrane-associated sites surrounding the nucleoid (PubMed:10921898). Required for the second pull step of DNA ejection (PubMed:17526715). Homodimer (PubMed:11169113, PubMed:17426023) (PubMed:15772069); homooligomer (PubMed:17426023). Interacts with DNA; one dsDNA binding subunit is constituted by three p16.7. dimers (PubMed:16275651, PubMed:17426023). Expressed abundantly in the early phase of the viral replicative cycle, especially at early infection times. Belongs to the phi29likevirus gp16.7 family.
