Vitamin D-binding protein [SEP] found in taxon
composed of 10 alpha helices, domain 2 of 9, and domain 3 of 4.
Function.
Vitamin D-binding protein belongs to the albumin gene family, together with human serum albumin and alpha-fetoprotein. It is a multifunctional protein found in plasma, ascitic fluid, cerebrospinal fluid and on the surface of many cell types. 
It is able to bind the various forms of vitamin D including ergocalciferol (vitamin D) and cholecalciferol (vitamin D), the 25-hydroxylated forms (calcifediol), and the
Vitamin D binding protein domain III
In molecular biology, Vitamin D binding protein domain III protein domain is predominantly found in Vitamin D binding proteins (DBP). Vitamin D-binding protein (DBP)(also referred to as Gc-globulin) is synthesized primarily in the liver. This entry outlines the domain III of DBP. Domain III (amino acid 379–458) is G-actin binding region located in the C-terminal. Domain (amino acids 373 to 403). This protein is found ubiquitously "in vivo" in
