BV/ODV
E26 Exhibits Bi-directional Trafficking (Dr.

Current
Research Projects: Jared Burks' research
with the baculovirus Autographa californica Nucleopolyhedrovirus
(AcMNPV) encodes a 26-kDa protein, BV/ODV E26 (E26). E26 is an envelope
protein found in both budded virus (BV) and occlusion derived virus (ODV)
envelopes. The different viral maturation processes allow for different
sources of viral envelopes, BV acquires envelopes at the plasma membrane
and ODV acquires envelopes in the nucleus. This results in bi-directional
trafficking of the E26 protein as BV matures early in infection and ODV
matures late. Transcription of the E26 gene is initiated from two promoters
at different time points during infection, an immediate early and late
promoter. My primary focus is to identify domains in E26 and proteins
responsible for trafficking E26 to membranes located in the nucleus. The
molecular pathways of integral membrane protein trafficking are not well
defined. This protein allows for a unique study approach into these
pathways due to its bi-directionality.
