Transcortin (corticosteroid-binding globulin, CBG, Serpin A6) (Hammond et al, 1987) is produced in the liver and functions as a plasma transporter of corticosteroids such as progesterone, aldosterone, cortisol and 11-deoxycorticosterone (Dunn et al, 1981). These hormones are biologically active when not bound to CBG therefore CBG may regulate the bioavailability of these hormones.
