Description générale

COL18A1 (collagen, type XVIII, α 1) codes for the α chain of collagen XVIII. It belongs to multiplexins (multiple triple-helix domains with interruptions) subgroup of collagen family. It is a proteoglycan collagen, which is non-fibrillar in nature. Its N- and C- termini are non-collagenous in nature and are intervened by alternating 10 collagenous and 9 non-collagenous repeats. The N-terminal contains thrombospondin-1-like motif, and a motif of 120 amino acids called frizzled motif, which has a cysteine-rich domain (CRD). This gene is located on human chromosome 21q22.3, and has 43 exons. Due to alternative splicing, this protein has three isoforms named, NC11-303, NC11-493 and NC11-728, which differ partly at their N-terminal and signal peptide. NC11-303 is expressed in fetal brain, kidney and retina; NC11-493 is predominantly expressed in adult and fetal liver, and NC11-728 is widely expressed, though predominant expression being in liver and lung.

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.

Actions biochimiques/physiologiques

COL18A1 (collagen, type XVIII, α 1) is responsible for defining the structure of retina and regulates the closure of neural tube. During embryogenesis, it is essential for normal eye development, and is expressed in the basement membrane of iris, vitreous and retina. It is also a part of the basement membrane of kidney, and is involved in teeth development. It is also involved in the migration of neurons. COL18A1 plays a role in normal development of brain, and mutations in this gene lead to structural abnormalities in brain. This protein shows marked increase in the cerebrospinal fluid (CSF) of patients with severe traumatic brain injury, and thus, COL18A1 might be involved in the response of central nervous system to any injury. Mutations in this gene lead to Knobloch Syndrome (KS), which is a rare autosomal recessive disorder.

Caractéristiques et avantages

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

Liaison

Corresponding Antigen APREST72542.

Forme physique

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
