• Function: Binds to the Fc region of immunoglobulins gamma. Low affinity receptor. By binding to IgG it initiates cellular responses against pathogens and soluble antigens. Promotes phagocytosis of opsonized antigens.
• KEGG Pathway:
  Phagosome (hsa04145)
  Osteoclast differentiation (hsa04380)
  Platelet activation (hsa04611)
  Fc gamma R-mediated phagocytosis (hsa04666)
  Leishmaniasis (hsa05140)
  Staphylococcus aureus infection (hsa05150)
  Tuberculosis (hsa05152)
  Systemic lupus erythematosus (hsa05322)
• Reactome Pathway:
  Regulation of actin dynamics for phagocytic cup formation (R-HSA-2029482)
  Role of phospholipids in phagocytosis (R-HSA-2029485)
  FCGR activation (R-HSA-2029481)
