FunctionFicolin (Fic) are defense proteins which belong to the innate immune system and recognize carbohydrate molecules[1]. 3 ficolins were identified in humans L-Fic or ficolin-2, H-Fic or ficolin-3 and M-Fic or ficolin-1.
DiseaseFn may play a role in inflammatory diseases, apoptosis, lupus, preeclampsia and IgA nephropathy[3]. Structural highlights. |
