Function
Ficolin (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.
Disease
Fn may play a role in inflammatory diseases, apoptosis, lupus, preeclampsia and IgA nephropathy[2].
Structural highlights
Human H-ficolin binding domain trimer.
Ca coordination site (PDB code 2j64).[3] Water molecules shown as red spheres.
