• Summary: CD16a (FCGR3A) and its homolog CD16b are receptors for the Fc portion of human IgG. In contrast to CD64, which is a high affinity Fc binding protein, both CD16a and CD16b can bind Fc portion of human IgG with relative low affinity. Human CD16a is expressed mainly on natural killer cells, macrophages, T cells, and monocytes. While human CD16b is expressed on Neutrophils and eosinophils. In human cells, a single nucleotide polymorphism (T230A) creates a high binding (176V) and a low binding (176F) variant. Clinically, mutations in CD16a have been linked to vulnerability to viral infections, alloimmune neonatal neutropenia, and systemic lupus erythematosus.
