Final answer:
CR1 is located on red blood cells and binds to antigens, but it does not lead to hemolysis.
Step-by-step explanation:
CR1, also known as complement receptor 1, is located on red blood cells. It binds to antigens and can't lead to hemolysis, which is the destruction of red blood cells. Hemolysis can occur when antibodies bind to red blood cells, but CR1 does not induce this process.
