General description
The gene SIGLEC14 (sialic acid binding Ig-like lectin 14) encodes a member of the Siglec family of sialic acid-binding lectins. It is found to be expressed mainly on granulocytes and monocytes. Human Siglec-14 is very similar to human Siglec-5 in terms of the sequence. The members of this family are receptors of the immunoglobulin (Ig) superfamily and are expressed on immune cells. The encoded protein has three Ig-like domains and preferentially binds to glycan. It also interacts with the activating adapter protein DAP12. The N-terminal region in both the proteins is almost identical and this indicates partial gene conversion between SIGLEC14 and SIGLEC5. The essential amino acid arginine of this protein, that participates in the recognition of sialic acid, is present in humans and is mutated in other apes.
Immunogen
Sialic acid-binding Ig-like lectin 14 precursor recombinant protein epitope signature tag (PrEST)
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.
Biochem/physiol Actions
Siglec-14 (sialic acid binding Ig-like lectin 14) enhances the secretion of TNF-α (tumor necrosis fector) stimulated by lipopolysaccharide in a monocytic cell line, indicating its role in bacterial infection. It is also involved in the ′infection-inflammation-exacerbation′ axis of COPD (chronic obstructive pulmonary disease) progression.
Features and Benefits
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.
Linkage
Corresponding Antigen APREST72436.
Physical form
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
