Mannose Receptor, C type 1 (MRC1) is a membrane receptor that mediates the endocytosis of glycoproteins by macrophages. MRC1 binds mannose structures on the surface of viruses, bacteria, and fungi to be neutralized by phagocytosis. Changes in MCR1 have been associated with multiple diseases including the development of leprosy, sarcoidosis, Alzheimer’s disease, and asthma. Human has more copies of MRC1 than any other primate which could have had important implications for the multiple diseases that MRC1 may be involved in.
