品种反应性 主要应用 宿主 格式 抗体类型 H WB Rb Serum Polyclonal Antibody 描述 产品目录编号 07-1318 描述 Anti-phospho-JAK2 (Tyr317) Antibody Alternate Names - tyrosine-protein kinase JAK2
- Janus kinase 2
- Janus kinase 2 (a protein tyrosine kinase)
背景信息 JAK2 (Janus Kinase 2) belongs to the emerging family of non-receptor Janus tyrosine kinases, which regulate a spectrum of cellular functions downstream of activated cytokine receptors in the lympho-hematopoietic system. Immunological stimuli, such as interferons and cytokines, induce recruitment of Stat transcription factors to cytokine receptor-associated JAK2. JAK2 then phosphorylates proximal Stat factors, which subsequently dimerize, translocate to the nucleus and bind to CIS elements upstream of target gene promoters to regulate transcription. The canonical JAK/Stat pathway is integral to maintaining a normal immune system by stimulating proliferation, differentiation, survival and host resistance to pathogens. Altering JAK/Stat signaling to reduce cytokine induced pro-inflammatory responses represents an attractive target for anti-inflammatory therapies. 产品信息 格式 Serum 演示 Rabbit serum with 0.05% sodium azide. 应用 应用 Detect phospho-JAK2 (Tyr317) using this Anti-phospho-JAK2 (Tyr317) Antibody validated for use in WB. 主要应用 - Western Blotting

UniProt汇总 FUNCTION: Plays a role in leptin signaling and control of body weight By similarity. Tyrosine kinase of the non-receptor type, involved in interleukin-3 and probably interleukin-23 signal transduction.
CATALYTIC ACTIVITY: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
SUBUNIT STRUCTURE: Interacts with SIRPA and SH2B1 By similarity. Interacts with IL23R, SKB1 and STAM2.
SUBCELLULAR LOCATION: Endomembrane system; Peripheral membrane protein By similarity. Note: Wholly intracellular, possibly membrane associated By similarity.
TISSUE SPECFICITY: Expressed in blood, bone marrow and lymph node.
DOMAIN: Possesses two phosphotransferase domains. The second one probably contains the catalytic domain By similarity, while the presence of slight differences suggest a different role for domain 1.
PTM: Leptin promotes phosphorylation on tyrosine residues, including phosphorylation on Tyr-813 By similarity.
INVOLVEMENT IN DISEASE: 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 [MIM:600880]. Budd-Chiari syndrome is a spectrum of disease states, including anatomic abnormalities and hypercoagulable disorders, resulting in hepatic venous outflow occlusion. Clinical manifestations observed in the majority of patients include hepatomegaly, right upper quadrant pain, and abdominal ascites.
Defects in JAK2 are associated with polycythemia vera (PV) [MIM:263300]. PV, the most common form of primary polycythemia, is caused by somatic mutation in a single hematopoietic stem cell leading to clonal hematopoiesis. PV is a myeloproliferative disorder characterized predominantly by erythroid hyperplasia, but also by myeloid leukocytosis, thrombocytosis, and splenomegaly. Familial cases of PV are very rare and usually manifest in elderly patients.
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 associated with familial myelofibrosis [MIM:254450]. Myelofibrosis with myeloid metaplasia is a myeloproliferative disease with annual incidence of 0.5-1.5 cases per 100,000 individuals and age at diagnosis around 60 (an increased prevalence is noted in Ashkenazi Jews). Clinical manifestations depend on the type of blood cell affected and 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.
