KIRK A1 HITOSHI HORI YR 2005 UL http://ar.iiarjournals.org/content/25/6A/3689.abstract AB The Gc protein (human group-specific component (Gc), a vitamin D-binding protein or Gc globulin), has important physiological functions that include involvement in vitamin D transport and storage, scavenging of extracellular G-actin, enhancement of the chemotactic activity of C5α for neutrophils in inflammation and macrophage activation (mediated by a GalNAc-modified Gc protein (GcMAF)). In this review, the structure and function of the Gc protein is focused on especially with regard to Gc genotyping and GcMAF precursor activity. A discussion of the research strategy “GcMAF as a target for drug discovery” is included, based on our own research. Copyright© 2005 International Institute of Anticancer Research (Dr. John G.
