Leptomycin B (LMB) is a specific inhibitor of Crm1-dependent
nuclear export of proteins. The replication of herpes simplex virus
(HSV) is normally highly sensitive to LMB; a resistant HSV variant,
however, was isolated by serial passages of the virus. Analysis of
marker transfer and viral DNA sequences revealed that a single amino
acid substitution within the ICP27 gene is responsible for conferring
this resistance.
