STRUTURE OF CORTICOSTEROID-BINDING GLOBULIN IN COMPLEX WITH CORTISOL
Overview
Corticosteroid-binding globulin (CBG) is a serine proteinase inhibitor, (serpin) family member that transports glucocorticoids in blood and, regulates their access to target cells. The 1.9 A crystal structure of rat, CBG shows that its steroid-binding site resembles the thyroxin-binding, site in the related serpin, thyroxin-binding globulin (TBG), and, mutagenesis studies have confirmed the contributions of key residues that, constitute the steroid-binding pocket. Unlike thyroxin-bound TBG, the, cortisol-bound CBG displays an "active" serpin conformation with the, proteinase-sensitive, reactive centre loop (RCL) fully expelled from the, regulatory beta-sheet A. Moreover, the CBG structure allows us to predict, that complete insertion of the proteolytically cleaved RCL into the serpin, ... [(full description)]
