Technical Data
Vitamin D Binding Protein (VDBP, VDB, DBP, DBP/GC, Gc Globulin, Group Specific Component, Group-specific Component, GC, hDBP, Vitamin D Binding alpha Globulin, VDBG)
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).
