Function
Non-receptor tyrosine kinase involved in various processes such as cell growth, development, differentiation or histone modifications. Mediates essential signaling events in both innate and adaptive immunity. In the cytoplasm, plays a pivotal role in signal transduction via its association with type I receptors such as growth hormone (GHR), prolactin (PRLR), leptin (LEPR), erythropoietin (EPOR), thrombopoietin receptor (MPL/TPOR); or type II receptors including IFN-alpha, IFN-beta, IFN-gamma and multiple interleukins (PubMed:15690087, PubMed:7615558, PubMed:9657743, PubMed:15899890). Following ligand-binding to cell surface receptors, phosphorylates specific tyrosine residues on the cytoplasmic tails of the receptor, creating docking sites for STATs proteins (PubMed:15690087, PubMed:9618263). Subsequently, phosphorylates the STATs proteins once they are recruited to the receptor. Phosphorylated STATs then form homodimer or heterodimers and translocate to the nucleus to activate gene transcription. For example, cell stimulation with erythropoietin (EPO) during erythropoiesis leads to JAK2 autophosphorylation, activation, and its association with erythropoietin receptor (EPOR) that becomes phosphorylated in its cytoplasmic domain (PubMed:9657743). Then, STAT5 (STAT5A or STAT5B) is recruited, phosphorylated and activated by JAK2. Once activated, dimerized STAT5 translocates into the nucleus and promotes the transcription of several essential genes involved in the modulation of erythropoiesis. Part of a signaling cascade that is activated by increased cellular retinol and that leads to the activation of STAT5 (STAT5A or STAT5B) (PubMed:21368206). In addition, JAK2 mediates angiotensin-2-induced ARHGEF1 phosphorylation (PubMed:20098430). Plays a role in cell cycle by phosphorylating CDKN1B (PubMed:21423214). Cooperates with TEC through reciprocal phosphorylation to mediate cytokine-driven activation of FOS transcription. In the nucleus, plays a key role in chromatin by specifically mediating phosphorylation of 'Tyr-41' of histone H3 (H3Y41ph), a specific tag that promotes exclusion of CBX5 (HP1 alpha) from chromatin (PubMed:19783980). Up-regulates the potassium voltage-gated channel activity of KCNA3 (PubMed:25644777).

Notes
JAK2 ELISA Kit (ab253224) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of JAK2 protein in cell lysate. It uses our proprietary SimpleStep ELISA® technology. Quantitate JAK2 with 129.3 pg/ml sensitivity.
SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:
- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips
A 384-well SimpleStep ELISA® microplate (Pre-coated 384 well Microplate SimpleStep ELISA® ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.
JAK2 is a non-receptor tyrosine kinase involved in processes such as cell growth, differentiation, histone modification, and mediation of innate and adaptive immunity signaling. Human, mouse and rat have high JAK2 protein sequence homology.

- Activity summary
JAK2 also known as Janus kinase 2 is a protein tyrosine kinase with a molecular weight of 125 kDa. It plays an essential mechanical role in the signaling pathways by acting as an intermediary between cell surface receptors and intracellular signaling molecules. The JAK2 protein binds to certain cytokine receptors facilitating signal transduction necessary for various cellular responses. JAK2 is expressed in many tissues including hematopoietic cells which are associated with the blood and immune systems.
- Biological function summary
JAK2 is important for transmitting signals that dictate cell growth survival and differentiation within the hematopoietic system. It operates bodily functions by forming complexes with specific phosphorylation sites on its associated receptors. Through this formation JAK2 influences the signaling cascade particularly by interacting with other signal transducers and activators where it phosphorylates and becomes activated. This action affects gene transcription directly correlated with cellular proliferation and differentiation processes.
- Pathways
The function of JAK2 integrates into the JAK-STAT signaling pathway which is an important pathway in the regulation of immune function growth and development. It works in conjunction with proteins such as STAT3 and STAT5 to transmit signals from cytokine receptors to the nucleus. This pathway critically impacts responses like inflammation and hematopoiesis aligning with its role in precursor proliferation within the bone marrow and various immune cells’ function.
- Associated diseases and disorders
JAK2 has significant implications in conditions like myeloproliferative neoplasms and polycythemia vera. Mutations in the JAK2 gene notably the JAK2 V617F mutation lead to uncontrolled cell division as they disrupt normal signaling mechanisms often resulting in blood cell disorders. In these contexts JAK2 interacts with proteins such as EpoR and MPL which play roles within these disease pathways. Understanding how JAK2 mutations contribute to disease progression offers pathways for targeted therapies.

Interpolated concentrations of native JAK2 in human K562 cell extract based on a 1,000 µg/mL extract, rat C6 cell extract based on a 1,000 µg/mL extract, and mouse NIH/3T3 based on a 500 μg/mL extract.
The concentrations of JAK2 were measured in duplicate and interpolated from the JAK2 standard curve and corrected for sample dilution. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean JAK2 concentration was determined to be 3,701 pg/mL in K562 cell extract, 2,823 pg/mL in C6 cell extract, and 1,339 pg/mL in NIH/3T3 cell extract.
