Polyhedrin
Promoter
From
Baculovirus - Baculovirus can synthesize polyhedrin protein in infected cells (baculovirus is an insect virus), so that polyhedrin makes upto 50% of the total protein in the cell, giving upto 1g of protein per liter of insect cell culture.
In view of this, the promoter has been used to construct expression vectors to allow high level of expression of any gene under the influence of this promoter. This is being used for developing biopesticides or even for production of specific chemicals in industry.
