Gc-globulin from human plasma is encoded by the gene GC, which is mapped to human chromosome 4q13.3.
Gc-Globulin, a member of the albumin superfamily, is the major plasma carrier of vitamin D and its metabolites. It is also, along with gelsolin, part of the extracellular actin scavenger system. Gc-globulin also binds monomeric actin (G-actin) with high affinity to scavenge actin released by necrotic cells, preventing its polymerization into filaments. Gc-globulin enhances the chemoattractant activity of C5a for inflammatory cells.
Gc-globulin or the vitamin D binding protein (DBP) is a 51-58 kDa multifunctional serum glycoprotein synthesized in large quantities by primarily in the liver. It is a member of the albumin gene family and has the characteristic multiple disulfide-bonded, triple domain structure.

Gc-globulin from human plasma has been used:

• as a fluorescent probe for G-actin staining
• as a fluorescent probe to monitor steady-state rate of actin filament disassembly
• as a calibrator for liquid chromatography with mass spectrometry (LC-MS/MS)

Gc-globulin is a multifunctional, albumin-like plasma protein that often requires cell surface binding to mediate some of its diverse functions. It has been used to anlayze its glycosylation patterns.

Single nucleotide polymorphism in the gene GC is associated with deficiency of 25-hydroxyvitamin D [25(OH)D].
