Function
Tyrosine kinase of the non-receptor type involved in numerous cytokines and interferons signaling, which regulates cell growth, development, cell migration, innate and adaptive immunity (PubMed:10542297, PubMed:10995743, PubMed:7657660, PubMed:7813427, PubMed:8232552). Plays both structural and catalytic roles in numerous interleukins and interferons (IFN-alpha/beta) signaling (PubMed:10542297). Associates with heterodimeric cytokine receptor complexes and activates STAT family members including STAT1, STAT3, STAT4 or STAT6 (PubMed:10542297, PubMed:7638186). The heterodimeric cytokine receptor complexes are composed of (1) a TYK2-associated receptor chain (IFNAR1, IL12RB1, IL10RB or IL13RA1), and (2) a second receptor chain associated either with JAK1 or JAK2 (PubMed:10542297, PubMed:25762719, PubMed:7526154, PubMed:7813427). In response to cytokine-binding to receptors, phosphorylates and activates receptors (IFNAR1, IL12RB1, IL10RB or IL13RA1), creating docking sites for STAT members (PubMed:7526154, PubMed:7657660). In turn, recruited STATs are phosphorylated by TYK2 (or JAK1/JAK2 on the second receptor chain), form homo- and heterodimers, translocate to the nucleus, and regulate cytokine/growth factor responsive genes (PubMed:10542297, PubMed:25762719, PubMed:7657660). Negatively regulates STAT3 activity by promototing phosphorylation at a specific tyrosine that differs from the site used for signaling (PubMed:29162862).

Notes
Phosphotyrosine TYK2 ELISA Kit (ab279961) is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated TYK2 protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.
This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-TYK2. An anti-TYK2 antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and phosphorylated and unphosphorylated TYK2 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-phosphotyrosine antibody is used to detect only tyrosine-phosphorylated protein. After washing away unbound antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of phospho-TYK2 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

- Activity summary
Tyrosine kinase 2 (TYK2) also known as JAK1B is a non-receptor tyrosine kinase that weighs approximately 134 kDa. It belongs to the Janus kinase (JAK) family which includes JAK1 JAK2 and JAK3. TYK2 is vital in signal transduction for several cytokine receptors. The expression of TYK2 occurs broadly in different tissues including immune system cells. It plays an important mechanical role in transferring signals from cell surface receptors to intracellular signaling pathways which modulates various physiological processes.
- Biological function summary
TYK2 mediates intracellular signaling that affects both innate and adaptive immune responses. It associates with cytokine receptors forming functional complexes that are critical for initiating JAK-STAT signaling. This type of signaling is responsible for regulating gene expression after cytokine binding. TYK2 is known for interacting with Type I interferons and interleukin-10 family cytokines indicating its importance in immune regulation.
- Pathways
TYK2 acts within the JAK-STAT pathway a fundamental signaling cascade triggered by various cytokines and growth factors. The JAK-STAT pathway includes key partners such as STAT1 STAT2 and STAT3 proteins which are phosphorylated by TYK2 to propagate signal transduction. Additionally TYK2 is involved in the 'intercept blocking buffer' mechanism that adjusts signal strength thereby ensuring appropriate cellular responses to external stimuli.
- Associated diseases and disorders
Altered TYK2 activity has associations with immune-related conditions like psoriasis and systemic lupus erythematosus. Dysregulation of TYK2 can lead to improper immune signaling which contributes to these autoimmune conditions. Furthermore TYK2 interacts with other Janus kinase family members including JAK1 and JAK3 which can influence its role in the pathogenesis of these diseases potentially offering targets for therapeutic intervention.
