Reaction: Ficolin-3 binds to molecular patterns on the target cell surface

- in pathway: Ficolins bind to repetitive carbohydrate structures on the target cell surface
Ficolin-3 (H-ficolin, FCN3, Hakata antigen) consists of a collagen-like strand and three C-terminal recognition domains, which bind to carbohydrates on the target surface. Circulating FCN3 is associated with mannan-binding lectin-associated serine proteases (MASP). Upon ligand binding the FCN3:MASP complex triggers activation of the lectin pathway (Matsushita et al. 2002, Teillet et al. 2008, Zacho et al. 2012). FCN3 can specifically recognize Aerococcus viridans (Tsujimura et al. 2002, Zacho et al. 2012) and binds patterns of bacterial polysaccharides such as d-fucose and galactose (Garlatti et al. 2007). In adition to pathogenic ligands, FCN3 was reported to bind apoptotic Jurkat cells (Kuraya et al. 2005).
