Domain Architecture (Details)
InterPro domains unassigned to SynO:
This cadherin domain is usually the most N-terminal copy of cadherin domains.
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.hich 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.hile 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.uggesting they may play an important role in the sorting of different cell types during morphogenesis.istogenesis and regeneration. They may also be involved in the regulation of tight and gap junctions.nd 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.adherins comprise a number of domains: classically.hese include a signal sequence; a propeptide of around 130 residues; a single transmembrane domain and five tandemly repeated extracellular cadherin domains. of which are cadherin repeats.nd the fifth contains 4 conserved cysteines and a N-terminal cytoplasmic domain . However.roteins 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.XNDNAPXF.nd DXD. Crystal structures have revealed that multiple cadherin domains form Ca2+-dependent rod-like structures with a conserved Ca2+-binding pocket at thedomain-domain interface. Cadherins depend on calcium for their function: calcium ions bind to specific residues in each cadherin repeat to ensure its proper folding.o confer rigidity upon the extracellular domain and is essential for cadherin adhesive function and for protection against protease digestion.
This domain of about 100 residues is found multiple (up to 35) copies in long proteins from several species of Vibrio.olwellia.radyrhizobium.nd Shewanella (hence the name VCBS) and in smaller copy numbers in proteins from several other bacteria. The large protein size and repeat copy numbers.pecies distribution.nd suggested activities of several member proteins suggests a role for this domain in adhesion.
