Opis

General description

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.[1] It is a member of the albumin gene family and has the characteristic multiple disulfide-bonded, triple domain structure.[2]

Gc-globulin from human plasma is encoded by the gene GC, which is mapped to human chromosome 4q13.3.

Application

Gc-globulin is a multifunctional, albumin-like plasma protein that often requires cell surface binding to mediate some of its diverse functions.[3] It has been used to anlayze its glycosylation patterns.

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)

Biochem/physiol Actions

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, a 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.

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