Function

Non-receptor tyrosine kinase involved in various processes such as cell cycle progression, apoptosis, mitotic recombination, genetic instability and histone modifications. In the cytoplasm, plays a pivotal role in signal transduction via its association with cytokine receptors, which constitutes an initiating step in signaling for many members of the cytokine receptor superfamily including the receptors for growth hormone (GHR), prolactin (PRLR), leptin (LEPR), erythropoietin (EPOR), granulocyte-macrophage colony-stimulating factor (CSF2), thrombopoietin (THPO) and multiple interleukins. Following stimulation with erythropoietin (EPO) during erythropoiesis, it is autophosphorylated and activated, leading to its association with erythropoietin receptor (EPOR) and tyrosine phosphorylation of residues in the EPOR cytoplasmic domain. Also involved in promoting the localization of EPOR to the plasma membrane. Also acts downstream of some G-protein coupled receptors. Plays a role in the control of body weight (By similarity). Mediates angiotensin-2-induced ARHGEF1 phosphorylation. 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.
Tissue specificity

Expressed in blood, bone marrow and lymph node.
Involvement in disease

Note=Chromosomal aberrations involving JAK2 are found in both chronic and acute forms of eosinophilic, lymphoblastic and myeloid leukemia. Translocation t(8;9)(p22;p24) with PCM1 links the protein kinase domain of JAK2 to the major portion of PCM1. Translocation t(9;12)(p24;p13) with ETV6.
Defects in JAK2 are a cause of susceptibility to Budd-Chiari syndrome (BCS) [MIM:600880]. It is a syndrome caused by obstruction of hepatic venous outflow involving either the hepatic veins or the terminal segment of the inferior vena cava. Obstructions are generally caused by thrombosis and lead to hepatic congestion and ischemic necrosis. Clinical manifestations observed in the majority of patients include hepatomegaly, right upper quadrant pain and abdominal ascites. Budd-Chiari syndrome is associated with a combination of disease states including primary myeloproliferative syndromes and thrombophilia due to factor V Leiden, protein C deficiency and antithrombin III deficiency. Budd-Chiari syndrome is a rare but typical complication in patients with polycythemia vera.
Defects in JAK2 are a cause of polycythemia vera (PV) [MIM:263300]. A myeloproliferative disorder characterized by abnormal proliferation of all hematopoietic bone marrow elements, erythroid hyperplasia, an absolute increase in total blood volume, but also by myeloid leukocytosis, thrombocytosis and splenomegaly.
Defects in JAK2 gene may be a cause of essential thrombocythemia (ET) [MIM:187950]. ET is characterized by elevated platelet levels due to sustained proliferation of megakaryocytes, and frequently lead to thrombotic and haemorrhagic complications.
Defects in JAK2 are a cause of myelofibrosis (MYELOF) [MIM:254450]. Myelofibrosis is a disorder characterized by replacement of the bone marrow by fibrous tissue, occurring in association with a myeloproliferative disorder. Clinical manifestations may include anemia, pallor, splenomegaly, hypermetabolic state, petechiae, ecchymosis, bleeding, lymphadenopathy, hepatomegaly, portal hypertension.
Defects in JAK2 are a cause of acute myelogenous leukemia (AML) [MIM:601626]. AML is a malignant disease in which hematopoietic precursors are arrested in an early stage of development.
Sequence similarities

Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily.
Contains 1 FERM domain.
Contains 1 protein kinase domain.
Contains 1 SH2 domain.
Domain

Possesses 2 protein kinase domains. The second one probably contains the catalytic domain, while the presence of slight differences suggest a different role for protein kinase 1.
Post-translational
modifications

Autophosphorylated, leading to regulate its activity. Leptin promotes phosphorylation on tyrosine residues, including phosphorylation on Tyr-813. Autophosphorylation on Tyr-119 in response to EPO down-regulates its kinase activity. Autophosphorylation on Tyr-868, Tyr-966 and Tyr-972 in response to growth hormone (GH) are required for maximal kinase activity.

Question

I purchased 12 antibodies from your company.
Some didn't work and I need your help.

I used mouse liver tissue. I attached our lab's protocol.
Apply 25ug of protein in each well.
The gel I used is NuPAGE 4-12% Bis-Tris Gel.
I tried 1:1000 dilution of JAK2 and 1:5000 of phospho JAK2 in 5%NFDM TBST.
Both didn't work. No bands, even with 2 hour exposure.

Please give me your advice.

Answer

Thank you for bringing this to our attention. I am sorry to read that two of the antibodies you purchased are not staining blots of your mouse liver samples.

I am assuming the transfer from gel to blot was effective, if your protocol worked with other blots of these samples.

I recommend stripping a blot and re-blocking with 1% BSA without detergent for one hour, and also diluting the antibodies in this 1% BSA solution, instead of non-fat dry milk. I also recommend trying the antibodies at higher concentrations, for instance 1/250 for anti-JAK2 ab39636, and 1/2000 for the phospho-Jak2 antibody, ab32101.

Please let me know the results. If this modification fails, I will be happy to provide replacements, or a credit or refund. The phosphorylation in the liver may be difficult to detect if it is not induced. If possible, I recommend including a positive control such as the treated mouse liver sample shown on the datasheet of ab68268.

Asked on Mar 13 2012

Answer

Thank you for your enquiry.

I can confirm that this antibody has been tested on the following and these would be suitable positive controls:

Rat uterine cell line Treated with 1µg/mL Prolactin for 1 hour.

Jurkat cell lysate treated with GM-CSF (Granulocyte-macrophage colony-stimulating factor) or Pervanadate

I am sorry we do not provide lysates of these cell lines that have beenpre treated. Unfortunately, we did not test any cell lines that do not require pretreatment. I was not able to find positive controls for phosphorylated Jak2 in the literature, and from what I find stimulation is required for expression of this phosphorylated state of the protein in cell culture.

I can suggest to do a further literature search for more information.

I am sorry we have not suitable positive controls to provide from our catalog on this occasion, however I hope this information is useful to you. If you have any further questions, please do not hesitate to contact me.

Thank you for contacting us. The treatment of PFA-fixed, paraffin embedded sections (IHC-P) before incubation with priamry antibody would include antigen retrieval, blocking of endogenous peroxidases (if HRP is being used for detection), and blocking of non-specific proteins. Here are the protocol details for the respective antibodies: ab30646, ab31370, ab39636, ab59389: 1. antigen retrieval: 10 mM citrate buffer (pH6.0) boil in pressure cooker 2. block with 3% H2O2 (in fresh methanol) for 15 minutes at room temperature 3. block with 3% BSA in TBS for 30 minutes ab6672: antigen retrieval: citrate buffer pH 6 and proteinase K digestion have been tried successfully as well as no antigen retrieval. 2. block with 3% hydrogen peroxide for 10 min 3. block with 1-10% Serum for up to 1 hour ab32101: 1. antigen retrieval:10 mM Sodium Citrate Buffer, pH 6.0 in rice cooker 2. block with 3% hydrogen peroxide for 10 min 3. block with PBS + 10% serum I hope this information is helpful to you.

Question

Dear Sirs, I am potentially very interested in purchasing this mAb but I would like first to know: 1) whether this mAb is specific for the Y1007-Y1008 phosphorylated form of JAK2 or also detects the non-phosphorylated form (could you please provide a western blot, as the one shown in the website is not informative in this regard?) 2) whether you had the chance to test this mAb also on formalin-fixed paraffin-embedded decalcified bone marrow biopsies; in fact, the additional decalcification step required by bone material often denatures epitopes otherwise resistant to formalin fixation and paraffin embedding 3) which tissues can be used as positive controls, besides lung adenocarcinoma 4) what is the frequency of positivity of lung adenocarcinoma ?

Asked on Oct 16 2006

Answer

Thank you for contacting us. In answer to your questions: 1. The antibody ab32101 is specific to the phosphorylated protein. We do not have another Western blot but we are confident, given the dot blot result, that this antibody will not recognize unphosphorylated JAK2. 2. We have not tested the antibody on bone marrow but our Abpromise guarantee covers this application. 3. Any carcinoma should serve well as a positive control: colon, breast, renal. 4. We do not know how often lung adenocarcinoma tissue reacts positively with this antibody. I hope this information helps. Please do not hesitate to contact us if you need any more advice or information.
