C-type lectin (CTL)/C-type lectin-like (CTLD) domain; CLECT: C-type lectin (CTL)/C-type lectin-like (CTLD) domain; protein domains homologous to the carbohydrate-recognition domains (CRDs) of the C-type lectins. This group is chiefly comprised of eukaryotic CTLDs, but contains some, as yet functionally uncharacterized, bacterial CTLDs. Many CTLDs are calcium-dependent carbohydrate binding modules; other CTLDs bind protein ligands, lipids, and inorganic surfaces, including CaCO3 and ice. Animal C-type lectins are involved in such functions as extracellular matrix organization, endocytosis, complement activation, pathogen recognition, and cell-cell interactions. For example: mannose-binding lectin and lung surfactant proteins A and D bind carbohydrates on surfaces (e.g. pathogens, allergens, necrotic, and apoptotic cells) and mediate functions associated with killing and phagocytosis; P (platlet)-, E (endothelial)-, and L (leukocyte)- selectins (sels) mediate the initial attachment, tethering, and rolling of lymphocytes on inflamed vascular walls enabling subsequent lymphocyte adhesion and transmigration. CTLDs may bind a variety of carbohydrate ligands including mannose, N-acetylglucosamine, galactose, N-acetylgalactosamine, and fucose. Several CTLDs bind to protein ligands, and only some of these binding interactions are Ca2+-dependent; including the CTLDs of Coagulation Factors IX/X (IX/X) and Von Willebrand Factor (VWF) binding proteins, and natural killer cell receptors. C-type lectins, such as lithostathine, and some type II antifreeze glycoproteins function in a Ca2+-independent manner to bind inorganic surfaces. Many proteins in this group contain a single CTLD; these CTLDs associate with each other through several different surfaces to form dimers, trimers, or tetramers, from which ligand-binding sites project in different orientations. Various vertebrate type 1 transmembrane proteins including macrophage mannose receptor, endo180, phospholipase A2 receptor, and dendritic and epithelial cell receptor (DEC205) have extracellular domains containing 8 or more CTLDs; these CTLDs remain in the parent model. In some members (IX/X and VWF binding proteins), a loop extends to the adjoining domain to form a loop-swapped dimer. A similar conformation is seen in the macrophage mannose receptor CRD4's putative non-sugar bound form of the domain in the acid environment of the endosome. Lineage specific expansions of CTLDs have occurred in several animal lineages including Drosophila melanogaster and Caenorhabditis elegans; these CTLDs also remain in the parent model.

C-type lectin-like domain (CTLD) of the type found in lectins TC14, TC14-2, TC14-3, and TC14-4 ...
 94-169 7.01e-04

C-type lectin-like domain (CTLD) of the type found in lectins TC14, TC14-2, TC14-3, and TC14-4 from the budding tunicate Polyandrocarpa misakiensis and PfG6 from the Acorn worm; CLECT_TC14_like: C-type lectin-like domain (CTLD) of the type found in lectins TC14, TC14-2, TC14-3, and TC14-4 from the budding tunicate Polyandrocarpa misakiensis and PfG6 from the Acorn worm. CTLD refers to a domain homologous to the carbohydrate-recognition domains (CRDs) of the C-type lectins. TC14 is homodimeric. The CTLD of TC14 binds D-galactose and D-fucose. TC14 is expressed constitutively by multipotent epithelial and mesenchymal cells and plays in role during budding, in inducing the aggregation of undifferentiated mesenchymal cells to give rise to epithelial forming tissue. TC14-2 and TC14-3 shows calcium-dependent galactose binding activity. TC14-3 is a cytostatic factor which blocks cell growth and dedifferentiation of the atrial epithelium during asexual reproduction. It may also act as a differentiation inducing factor. Galactose inhibits the cytostatic activity of TC14-3. The gene for Acorn worm PfG6 is gill-specific; PfG6 may be a secreted protein.
