JAK2 ELISA Kit for Human, Mouse, Rat

This gene product is a protein tyrosine kinase involved in a specific subset of cytokine receptor signaling pathways. It has been found to be constituitively associated with the prolactin receptor and is required for responses to gamma interferon. Mice that do not express an active protein for this gene exhibit embryonic lethality associated with the absence of definitive erythropoiesis. [provided by RefSeq, Jul 2008]

JAK2: a non-receptor tyrosine-kinase involved in a specific subset of cytokine receptor signaling pathways, including IL-3, -5 and GM-CSF. Interacts with IL23R, SKB1 and STAM2. It has been found to be constitutively associated with the prolactin receptor and is required for responses to gamma interferon. Mice that do not express an active protein for this gene exhibit embryonic lethality associated with the absence of definitive erythropoiesis. Fusion of Jak2 to TEL1 (ETV6) by t(9;12)(p24;p13) causes myeloproliferative disease in humans and mouse models. The Jak inhibitor AG490 inhibits constitutive Jak2 phosphorylation and causes apoptosis in cells from breast cancer and relapsing acute lymphoblastic leukemia. A single activating mutation is associated with several hematological malignancies. Inhibitor: AG490.
