J Virol
. 2008 Oct;
83(1):37-46.
PMID: 18945763
Proper folding of newly synthesized viral proteins in the cytoplasm is a prerequisite for the formation of infectious virions. The major capsid protein Vp1 of simian virus 40 forms a...

Virus Res
. 2006 Nov;
124(1-2):226-30.
PMID: 17112617
To establish viral infection, SV40 must expose nuclear localization signals (NLSs) that are internal in the virion architecture in order to enter the nucleus via interaction with the host's nuclear...
