Vitamin D binding protein (DBP), also known as the group-specific component of serum (Gc-globulin), is a member of the albumin, α-fetoprotein, and α-albumin multigene family (1, 2). DBP is a highly polymorphic serum protein predominantly synthesized in the liver as a single-chain glycoprotein of ∼58 kDa (3). The serum concentration of human DBP is 4–8 μΜ and its serum halflife is 2.5–3 days. DB...
