Domain Architecture (Details)
InterPro domains assigned to SynO:
Laminins are large heterotrimeric glycoproteins involved in basement membrane function . The laminin globular (G) domain can be found in one to several copies in various laminin family members.ncluding a large number of extracellular proteins. The C-terminus of the laminin alpha chain contains a tandem repeat of five laminin G domains.hich are critical for heparin-binding and cell attachment activity . Laminin alpha4 is distributed in a variety of tissues including peripheral nerves.orsal root ganglion.keletal muscle and capillaries; in the neuromuscular junction.t is required for synaptic specialisation . The structure of the laminin-G domain has been predicted to resemble that of pentraxin .Laminin G domains can vary in their function.nd a variety of binding functions have been ascribed to different LamG modules. For example.he laminin alpha1 and alpha2 chains each have five C-teminal laminin G domains.here only domains LG4 and LG5 contain binding sites for heparin.ulphatides and the cell surface receptor dystroglycan . Laminin G-containing proteins appear to have a wide variety of roles in cell adhesion.ignalling.igration.ssembly and differentiation. Proteins with laminin-G domains include:Laminin.Merosin.Agrin.Neurexins.Vitamin K dependent protein S.Sex steroid binding protein SBP/SHBG.Drosophila proteins Slit.rumbs.at.several proteoglycan precursors.

Lectins and glucanases exhibit the common property of reversibly binding to specific complex carbohydrates. The lectins/glucanases are a diverse group of proteins found in a wide range of species from prokaryotes to humans. The different family members all contain a concanavalin A-like domain.hich consists of a sandwich of 12-14 beta strands in two sheets with a complex topology. Members of this family are diverse.nd include the lectins: legume lectins.ereal lectins.iral lectins.nd animal lectins. Plant lectins function in the storage and transport of carbohydrates in seeds.he binding of nitrogen-fixing bacteria to root hairs.he inhibition of fungal growth or insect feeding.nd in hormonally regulated plant growth . Protein members include concanavalin A (Con A).avin.solectin I.ectin IV.oybean agglutinin and lentil lectin. Animal lectins include the galectins.hich are S-type lactose-binding and IgE-binding proteins such as S-lectin.LC protein.alectin1.alectin2.alectin3 CRD.nd Congerin I . Other members with a Con A-like domain include the glucanases and xylanases. Bacterial and fungal beta-glucanases.uch as Bacillus 1-3.-4-beta-glucanse.arry out the acid catalysis of beta-glucans found in microorganisms and plants . Similarly.appa-Carrageenase degrades kappa-carrageenans from marine red algae cell walls . Xylanase and cellobiohydrolase I degrade hemicellulose and cellulose.espectively . There are many Con A-like domains found in proteins involved in cell recognition and adhesion. For example.everal viral and bacterial toxins carry Con A-like domains. Examples include the Clostridium neurotoxins responsible for the neuroparalytic effects of botulism and tetanus . The Pseudomonas exotoxin A. virulence factor which is highly toxic to eukaryotic cells.ausing the arrest of protein synthesis.ontains a Con A-like domain involved in receptor binding . Cholerae neuraminidase can bind to cell surfaces.ossibly through their Con A-like domains.here they function as part of a mucinase complex to degrade the mucin layer of the gastrointestinal tract . The rotaviral outer capsid protein.P4.as a Con A-like sialic acid binding domain.hich functions in cell attachment and membrane penetration . Con A-like domains also play a role in cell recognition in eukaryotes. Proteins containing a Con A-like domain include the sex hormone-binding globulins which transport sex steroids in blood and regulate their access to target tissues .aminins which are large heterotrimeric glycoproteins involved in basement membrane architecture and function .eurexins which are expressed in hundreds of isoforms on the neuronal cell surface.here they may function as cell recognition molecules and sialidases that are found in both microorganisms and animals.nd function in cell adhesion and signal transduction . Other proteins containing a Con A-like domain include pentraxins and calnexins. The pentraxin PTX3 is a TNFalpha-induced.ecreted protein of adipose cells produced during inflammation . The calnexin family of molecular chaperones is conserved among plants.ungi.nd animals. Family members include Calnexin. type-I integral membrane protein in the endoplasmic reticulum which coordinates the processing of newly synthesized N-linked glycoproteins with their productive folding.almegin. type-I membrane protein expressed mainly in the spermatids of the testis.nd calreticulin. soluble ER lumenal paralog .
