Microviruses contains two spike proteins, the major spike protein,
depicted above, and the minor spike protein, also called the DNA pilot
protein. Currently we are using dominant negative DNA pilot proteins to
investigate how it pilots the infecting viral DNA from the outer
membrane to the site of DNA replication on the inner membrane. Assembly
and eclipse mechanisms are being investigated by constructing chimeric
virions by interchanging major spike proteins between related
microviruses.
