The location of nucleosomes in SV40 virions and minichromosomes isolated during infection were determined by next generation sequencing (NGS). The patterns of reads within the regulatory region of chromatin from wild-type virions indicated that micrococcal nuclease-resistant nucleosomes were specifically positioned at nt 5223 and nt 363, while in minichromosomes isolated 48 h post-infection we observed...
The foot-and-mouth disease virus (FMDV) leader protease (Lpro) inhibits host translation and transcription affecting the expression of several factors involved in innate immunity. In this study, we have identified the host transcription factor ADNP (activity dependent neuroprotective protein) as an Lpro interacting protein by mass spectrometry. We show that Lpro can bind to ADNP in vitro and in cell...
Human papillomaviruses are causative agents in several human diseases ranging from genital warts to ano-genital and oropharyngeal cancers. Currently only symptoms of HPV induced disease are treated; there are no antivirals available that directly target the viral life cycle. Previously, we determined that the cellular protein TopBP1 interacts with the HPV16 replication/transcription factor E2. This...
African swine fever virus threatens pig production worldwide due to the lack of vaccines, for which generation of both deletion and insertion mutants is considered. For development of the latter, operational ASFV promoters of different temporal regulation and strengths are desirable. We therefore compared the capacities of putative promoter sequences from p72, CD2v, p30, viral DNA polymerase and U104L...
The 3′-untranslated region (UTR) of the non-segmented, negative-strand (NNS) RNA viral genome is called the leader sequence, and functions as the promoter for viral replication and transcription. NNS RNA viruses also use the sequence as a template to synthesize leader RNAs (leRNAs) with unknown functions. Borna disease virus (BDV) is unique because it establishes a persistent infection and replicates...
