Abstract

baculovirus
The structure-function relationship of the oligomeric unactivated glucocorticoid receptor is not fully understood. An essential step in the process of understanding such a relationship involves the production of large quantities of the receptor. Using a baculovirus expression system we have been able to overproduce a recombinant rat glucocorticoid receptor (rGR). A cDNA coding for the entire rGR was introduced into the genome of the wild type baculovirus, Autographa californica nuclear polyhedrosis virus, by an in vivo recombination event. Based on specific steroid binding, insect cells infected with the recombinant baculovirus expressed 1-3 x 10 super(6) receptor molecules/cell which is 15-45 times more than that expressed normally in a hepatocyte.
