General description

AATK (apoptosis-associated tyrosine kinase) was recently identified in 32Dcl3 mouse myeloid cells, which were subjected to IL (interleukin)-3 withdrawal and undergoing apoptosis. This protein is composed of a putative tyrosine kinase domain, and has multiple Src homology 2 (SH2) and (SH3)-binding motifs. This protein is predominantly expressed in brain, and is localized to the cytoplasm. It is an active, non-receptor kinase. This protein is composed of 1316 amino acids and has a molecular weight of 145kDa. The N-terminal of this protein shows high homology to tyrosine kinases. This gene is localized to human chromosome 17q25.3.

Immunogen

Serine/threonine-protein kinase LMTK1 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

AATK (apoptosis-associated tyrosine kinase) faciliates the differentiation of neurons when stimulated by all-trans retinoic acid (RA), 12-O-Tetradecanoyl phorbol 13-acetate (TPA) and IGF-I (insulin like growth factor-I). it induces neuronal differentiation even in the absence of these agents. It is an essential element for the induction of apoptosis and growth arrest in myeloid precursor cells. The expression of AATK mRNA was significantly elevated in cultured cerebral granule cells during apoptosis, suggesting this protein plays an important role in neuronal apoptosis. In developing neurons, this protein is involved in the extension of neurites through its tyrosine kinase activity.

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 APREST71460.

Physical form

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