Description: | Many of these domains function as calcium-dependent carbohydrate binding modules. |
Interpro abstract (IPR001304): | A number of different families of proteins share a conserved domain which was first characterised in some animal lectins and which seem to function as a calcium-dependent carbohydrate-recognition domain [ (PUBMED:3290208) (PUBMED:8341801) ]. This domain, which is known as the C-type lectin domain (CTL) or as the carbohydrate-recognition domain (CRD), consists of about 110 to 130 residues. There are four cysteines which are perfectly conserved and involved in two disulphide bonds. There are proteins with modules similar in overall structure to CRDs that serve functions other than sugar binding. Therefore, a more general term C-type lectin-like domain was introduced to refer to such domains, although both terms C-type lectin and C-type lectin-like are sometimes used interchangeably [ (PUBMED:16336259) ]. C-type lectins can be further divided into seven subgroups based on additional non-lectin domains and gene structure: (I) hyalectans, (II) asialoglycoprotein receptors, (III) collectins, (IV) selectins, (V) NK group transmembrane receptors, (VI) macrophage mannose receptors, and (VII) simple (single domain) lectins [ (PUBMED:15476922) ]. Lectins are a diverse group of proteins, both in terms of structure and activity. Carbohydrate binding ability may have evolved independently and sporadically in numerous unrelated families, where each evolved a structure that was conserved to fulfil some other activity and function. In general, animal lectins act as recognition molecules within the immune system, their functions involving defence against pathogens, cell trafficking, immune regulation and the prevention of autoimmunity [ (PUBMED:14519388) ]. |

- Display abstract
Lectins can be found in many organisms and are involved in a multitude of cellular processes that depend on specific recognition of complex carbohydrates. The stereochemical principles underlying the recognition process have been the subject of extensive biochemical and structural studies. When examined from the viewpoint of the bound sugar, the structural information accumulated so far on lectins and other proteins that are specific to galactose and glucose (or mannose), provides suggestive evidence for distinct ligand-dependent distribution of hydrogen-bond partners in the combining site.

- Display abstract
Lectins are responsible for cell surface sugar recognition in bacteria, animals, and plants. Examples include bacterial toxins; animal receptors that mediate cell-cell interactions, uptake of glycoconjugates, and pathogen neutralization; and plant toxins and mitogens. The structural basis for selective sugar recognition by members of all of these groups has been investigated by x-ray crystallography. Mechanisms for sugar recognition have evolved independently in diverse protein structural frameworks, but share some key features. Relatively low affinity binding sites for monosaccharides are formed at shallow indentations on protein surfaces. Selectivity is achieved through a combination of hydrogen bonding to the sugar hydroxyl groups with van der Waals packing, often including packing of a hydrophobic sugar face against aromatic amino acid side chains. Higher selectivity of binding is achieved by extending binding sites through additional direct and water-mediated contacts between oligosaccharides and the protein surface. Dramatically increased affinity for oligosaccharides results from clustering of simple binding sites in oligomers of the lectin polypeptides. The geometry of such oligomers helps to establish the ability of the lectins to distinguish surface arrays of polysaccharides in some instances and to crosslink glycoconjugates in others.

- Display abstract
Collectins are humoral lectins found in mammals and birds. They are oligomers whose subunits comprise three polypeptide chains each containing a collagenous section and a C-terminal lectin domain. They are related structurally and functionally to the first component of the classical complement pathway, C1q, and seem to serve important roles in innate immunity through opsonization and complement activation. The lectin domains bind carbohydrates on microorganisms, while the collagenous regions are ligands for the collectin receptor on phagocytes and also mediate C1q-independent activation of the classical complement pathway.
