WebAug 10, 2011 · Introduction. Adeno-associated virus type 2 (AAV) is a non-pathogenic human Parvovirus of the Dependovirus genus that relies on a co-infecting helper virus such as Adenovirus or Herpes simplex virus for productive replication.

"Rolling hairpin replication (RHR) is a unidirectional, strand displacement form of DNA replication used by parvoviruses, a group of viruses that constitute the family Parvoviridae. Parvoviruses have linear, single-stranded DNA (ssDNA) genomes in which the coding portion of the genome is flanked by telomeres … See more Parvoviruses are a family of DNA viruses that have single-stranded DNA (ssDNA) genomes enclosed in rugged, icosahedral protein capsids 18–26 nanometers (nm) in diameter. Unlike most other ssDNA viruses, which have … See more Upon cell entry, a tether about 24 nucleotides in length that attaches the viral protein NS1, essential in replication, to the virion is cleaved off the virion to be reattached later. … See more The right-end hairpin of MVM contains 248 nucleotides organized into a cruciform shape. This region is almost perfectly basepaired, with just … See more In negative-sense MVM genomes, the left-end hairpin is 121 nucleotides in length and exists in a single flip sequence orientation. This telomere is Y-shaped and contains small internal palindromes that fold into the "ears" of the Y, a duplex stem region 43 … See more The entire process of rolling hairpin replication, which has distinct, sequential stages, can be summarized as follows: • 1. The coding portion of the genome is replicated, starting from the 3′-end of the 3′ hairpin, which acts as a primer, and continues until the … See more Once an infected cell enters S-phase, parvovirus genomes are converted to their duplex form by host replication machinery, and mRNA that encodes non-structural (NS) proteins is transcribed starting from a viral promoter (P4 for MVM). One of these NS proteins is … See more Following nicking, a replication fork is established at the newly exposed 3′ nucleotide that proceeds to unfold and copy the right-end hairpin through a series of melting and reannealing reactions. This process begins once NS1 nicks the inboard end of the … See more " - Rolling hairpin replication aav
