Cadherins are calcium dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. May associate with arm neural isoform and participate in the transmission of developmental information. Drosophila melanogaster (taxid: 7227)

>PF00028 Cadherin: Cadherin domain; InterPro: IPR002126 Cadherins are a family of adhesion molecules that mediate Ca2+-dependent cell-cell adhesion in all solid tissues of the organism which modulate a wide variety of processes including cell polarisation and migration [, ,]
Cadherin-mediated cell-cell junctions are formed as a result of interaction between extracellular domains of identical cadherins, which are located on the membranes of the neighbouring cells. The stability of these adhesive junctions is ensured by binding of the intracellular cadherin domain with the actin cytoskeleton. There are a number of different isoforms distributed in a tissue-specific manner in a wide variety of organisms. Cells containing different cadherins tend to segregate in vitro, while those that contain the same cadherins tend to preferentially aggregate together. This observation is linked to the finding that cadherin expression causes morphological changes involving the positional segregation of cells into layers, suggesting they may play an important role in the sorting of different cell types during morphogenesis, histogenesis and regeneration. They may also be involved in the regulation of tight and gap junctions, and in the control of intercellular spacing. Cadherins are evolutionary related to the desmogleins which are component of intercellular desmosome junctions involved in the interaction of plaque proteins. Structurally, cadherins comprise a number of domains: classically, these include a signal sequence; a propeptide of around 130 residues; a single transmembrane domain and five tandemly repeated extracellular cadherin domains, 4 of which are cadherin repeats, and the fifth contains 4 conserved cysteines and a N-terminal cytoplasmic domain []. However, proteins are designated as members of the broadly defined cadherin family if they have one or more cadherin repeats. A cadherin repeat is an independently folding sequence of approximately 110 amino acids that contains motifs with the conserved sequences DRE, DXNDNAPXF, and DXD. Crystal structures have revealed that multiple cadherin domains form Ca2+-dependent rod-like structures with a conserved Ca2+-binding pocket at the domain-domain interface. Cadherins depend on calcium for their function: calcium ions bind to specific residues in each cadherin repeat to ensure its proper folding, to confer rigidity upon the extracellular domain and is essential for cadherin adhesive function and for protection against protease digestion.; GO: 0005509 calcium ion binding, 0007156 homophilic cell adhesion, 0016020 membrane; PDB: 2A4E_A 2A4C_B 2O72_A 2QVI_A 1NCJ_A 3Q2W_A 3Q2N_A 3LNH_B 3LNI_A 3Q2L_A ....
This domain of about 100 residues is found multiple (up to 35) copies in long proteins from several species of Vibrio, Colwellia, Bradyrhizobium, and Shewanella (hence the name VCBS) and in smaller copy numbers in proteins from several other bacteria. The large protein size and repeat copy numbers, species distribution, and suggested activities of several member proteins suggests a role for this domain in adhesion.
This model represents a domain of about 143 amino acids that may occur singly or in up to 23 tandem repeats in very large proteins in the genus Vibrio, and in related species such as Legionella pneumophila, Photobacterium profundum, Rhodopseudomonas palustris, Shewanella pealeana, and Aeromonas hydrophila. Proteins with these domains represent a subset of a broader set of proteins with a particular signal for type 1 secretion, consisting of several glycine-rich repeats modeled by pfam00353, followed by a C-terminal domain modeled by TIGR03661. Proteins with this domain tend to share several properties with the RtxA (Repeats in Toxin) protein of Vibrio cholerae, including a large size often containing tandemly repeated domains and a C-terminal signal for type 1 secretion.
Cadherin-homologous domains present in metazoan dystroglycans and alpha/epsilon sarcoglycans, yeast Axl2p and in a very large protein from magnetotactic bacteria. Likely to bind calcium ions.
