Abstract excerpt
Human M-ficolin is a pathogen-associated molecular recognition molecule in the innate immune system, and it binds to some sugars, such as GlcNAc (N-acetylglucosamine), on pathogen surfaces. From previous structural and functional studies of the FD1 (M-ficolin fibrinogen-like domain), we proposed that the ligand-binding region of FD1 exists in a conformational equilibrium between active and non-active states...
