Fibronectin Type III Domain
The Fibronectin type III domain is an evolutionarily conserved protein domain that is widely found in animal proteins. The fibronectin protein in which this domain was first identified contains 16 copies of this domain. The domain is about 100 amino acids long and possesses a beta sandwich structure. Of the three fibronectin-type domains, type III is the only one without disulfide bonding present. Fibronectin domains are found in a wide variety of extracellular proteins. They are widely distributed in animal species, but also found sporadically in yeast, plant and bacterial proteins.

Protein Domain
In molecular biology, a protein domain is a region of a protein's polypeptide chain that is self-stabilizing and that folds independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains, and a domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions. In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length. The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium-binding EF hand domain of calmodulin. Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins. Background The concept of the domain was first proposed in 1973 by Wetlaufer aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CNTN2
Contactin-2 is a protein that in humans is encoded by the ''CNTN2'' gene. Function The protein encoded by this gene is a member of the immunoglobulin superfamily. It is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system. It may also be involved in glial tumorigenesis and may provide a potential target for therapeutic intervention.

Deleted In Colorectal Cancer
Netrin receptor DCC, also known as DCC, or colorectal cancer suppressor is a protein which in humans is encoded by the ''DCC'' gene. DCC has long been implicated in colorectal cancer and its previous name was ''Deleted in colorectal carcinoma''. Netrin receptor DCC is a single transmembrane receptor. Since it was first discovered in a colorectal cancer study in 1990, ''DCC'' has been the focus of a significant amount of research. ''DCC'' held a controversial place as a tumour suppressor gene for many years, and is well known as an axon guidance receptor that responds to netrin-1. More recently DCC has been characterized as a dependence receptor, and many hypotheses have been put forward that have revived interest in ''DCCs candidacy as a tumour suppressor gene, as it may be a ligand-dependent suppressor that is frequently epigenetically silenced. Background Early studies of colorectal tumours found that allelic deletions of segments of chromosome 18q occur in a very high perce ...

CSF3R
The granulocyte colony-stimulating factor receptor (G-CSF-R) also known as CD114 (Cluster of Differentiation 114) is a protein that in humans is encoded by the ''CSF3R'' gene. G-CSF-R is a cell-surface receptor for the granulocyte colony-stimulating factor (G-CSF). The G-CSF receptors belongs to a family of cytokine receptors known as the '' hematopoietin receptor family''. The granulocyte colony-stimulating factor receptor is present on precursor cells in the bone marrow, and, in response to stimulation by G-CSF, initiates cell proliferation and differentiation into mature neutrophilic granulocytes and macrophages. The G-CSF-R is a transmembrane receptor that consists of an extracellular ligand-binding portion, a transmembrane domain, and the cytoplasmic portion that is responsible for signal transduction. GCSF-R ligand-binding is associated with dimerization of the receptor and signal transduction through proteins including Jak, Lyn, STAT, and Erk1/2. Isoforms The class IV ...

CRLF3
Cytokine receptor-like factor 3 is a protein that in humans is encoded by the ''CRLF3'' gene. Model organisms Model organisms have been used in the study of CRLF3 function. A conditional knockout mouse line, called ''Crlf3tm1a(KOMP)Wtsi'' was generated as part of the International Knockout Mouse Consortium program, a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists. Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion. Twenty six tests were carried out and two significant phenotypes were reported. Homozygous mutant female adults had a significant increase in circulating levels of fructosamine, while mutants of both sexes had decreased platelet cell numbers. Function Although CRLF3 signaling pathways have not yet been fully characterized it is very likely that CRLF3 is a neuroprotective erythropoietin receptor.

COL7A1
Collagen alpha-1(VII) chain is a protein that in humans is encoded by the ''COL7A1'' gene. It is composed of a triple helical, collagenous domain flanked by two non-collagenous domains, and functions as an anchoring fibril between the dermal-epidermal junction in the basement membrane. Mutations in COL7A1 cause all types of Dystrophic Epidermolysis Bullosa, dystrophic epidermolysis bullosa, and the exact mutations vary based on the specific type or subtype. It has been shown that interactions between the NC-1 domain of collagen VII and several other proteins, including Laminin, laminin-5 and Type IV collagen, collagen IV, contribute greatly to the overall stability of the basement membrane. Structure Type VII collagen is composed of three main domains in the following order: a non-collagenous domain, abbreviated NC-1; a collagenous domain; and a second non-collagenous domain, NC-2.
