Anti-SAMD4A antibody produced in rabbit

HPA043061    Human Protein Atlas characterization data

Sterile Α motif domain containing 4A (SAMD4A), also known as SMAUG, is encoded by the gene mapped to human chromosome 14. It belongs to RNA-binding proteins (RBPs) family and is produced during synaptogenesis. Mammalian SAMD4A is expressed mainly in central nervous system and is absent in nonneuronal cell lines.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

Sterile alpha motif domain containing 4A (SAMD4A) plays a vital role in RNA granule formation and represses mRNA carrying smaug recognition element (SRE) motifs at the synapse in neurons. SAMD4A restores translational activity of CUGBP1, which is associated with the pathogenesis of myotonic dystrophy type 1 (DM1). Thus, SAMD4A can be used as a potent therapeutic for DM1.

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.

Corresponding Antigen APREST83921.

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