FcR Receptor

An Fc receptor is a protein found on the surface of certain cells - including B lymphocytes, natural killer cells, macrophages, neutrophils, and mast cells - that contribute to the protective functions of the immune system. Its name is derived from its binding specificity for a part of an antibody known as the Fc (Fragment, crystallizable) region.
