Independent contributions of polyomavirus middle T and small T to the regulation of early and late gene expression and DNA replication.

abstract：:An unusually long noncoding sequence is located between the N gene of Borna disease virus (BDV) and the genes for regulatory factor X and polymerase cofactor P. Most of these nucleotides are transcribed and seem to control translation of the bicistronic X/P mRNA. We report here that Vero cells persistently infected wi...
