Collectin-11 (Colec11)

Calcium-dependent lectin that binds self and non-self glycoproteins presenting high mannose oligosaccharides with at least one terminal alpha-1,2-linked mannose epitope. Primarily recognizes the terminal disaccharide of the glycan.

Also recognizes a subset of fucosylated glycans and lipopolysaccharides. Plays a role in innate immunity through its ability to bind non-self sugars presented by microorganisms and to trigger the complement through the recruitment of MAPS1.
