Protein Information
Name GC
Function Multifunctional protein found in plasma, ascitic fluid, cerebrospinal fluid, and urine and on the surface of many cell types. In plasma, it carries the vitamin D sterols and prevents polymerization of actin by binding its monomers. DBP associates with membrane-bound immunoglobulin on the surface of B-lymphocytes and with IgG Fc receptor on the membranes of T-lymphocytes.
Cellular Location Secreted.

Vitamin D-binding protein (VDBP, DBP, Gc) is a multifunctional plasma protein that has many physiologically important functions, ranging from transporting vitamin D3 metabolites, binding and sequestering globular actin and binding fatty acids to functioning in the immune system. It is a member of a multigene family including alpha-fetoprotein and albumin. It is a serum glycoprotein that reversibly binds and transports vitamin D and its metabolites to target cells. VDBP has a triple domain modular structure with extensive disulfide bonding that is characteristic of this protein family. VDBP receptors are constitutively expressed by malignant B-cells and in a transitory form by normal B-lymphocytes undergoing mitogen-induced activation (1-4).
