The immunoglobulin superfamily is a large category of proteins defined by their structural similarity to immunoglobulins. The majority of these proteins are involved in protein-protein binding as receptors, antibodies or cell adhesion molecules. The I-type lectins are a subset of the immunoglobulin superfamily that are capable of carbohydrate-protein interactions. There are I-type lectins recognizing sialic acids, other sugars and glycosaminoglycans. The occurrence, structure, binding properties and (potential) biological functions of the I-type lectins are reviewed here.
