Decay-accelerating factor (DAF) is a protein that plays a critical role in regulating the complement system by preventing the formation of the C3 convertase enzyme complex. By inhibiting this enzyme's activity, DAF helps to control complement activation, protecting host cells from damage that can occur due to excessive or uncontrolled complement activity. It is particularly important for maintaining self-tolerance and preventing damage to healthy tissues during immune responses.
