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

TYK2 (Tyrosine kinase 2) plays an important role in cell signaling by multiple cytokines via the JAK-STAT pathway. Tyk2 interacts with type I IFN, p40-sharing IL-12 and IL-23, IL-6, and IL-10 family receptors and helps in immunomodulation. On binding, TYK2 is phosphorylated and co-activated with JAK1 and/or JAK2. It has been suggested that TYK2 is required for the surface expression of human IL-10R as well as human type I IFNR. TYK2 is also involved in the differentiation of immune cells, such as B cells, T helper cells and natural killer cells. Abnormal TYK2 expression is implicated in the etiology of several auto-immune diseases such as multiple sclerosis, rheumatoid arthritis and systemic lupus erythematosus. Studies show that TYK2 rs34536443 polymorphism is associated with endometriosis and related infertility.

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.

General description

Tyrosine kinase 2 (TYK2) belongs to the Janus Kinase (Jak) family and is a non-receptor tyrosine kinase. TYK2 gene maps to chromosome 19p13.2 and is expressed in non-hematopoietic as well as hematopoietic cell lines. TYK2 gene has high variations in human population, with more than 100 non-synonymous TYK2 gene variants present.
