DOK2 Antibody

Docking proteins interact with receptor tyrosine kinases and mediate particular biological responses using signal transduction. Dok-2 acts as a multiple docking protein downstream of receptor or non-receptor tyrosine kinases. By this mechanism it acts to negatively regulate signal transduction and cell proliferation controlled by cytokines in a feedback loop. Dok-2 is highly expressed in cells and tissues of hematopoietic origin as well as in lung. Expression of bcr/abl induces additional tyrosine phosphorylation of the Dok1 and Dok2 proteins and their association with Ras-GAP. Thus, it is suspected that DOK association regulates GAP activity toward Ras and that the Dok proteins serve as mediators of bcr-abl signaling. The role of Dok proteins in bcr-abl regulation may also be implicated in chronic myelogenous leukemia (CML), which is characterized by a Philadelphia chromosome translocation t (9;22) . Such a mutation would result in a p210-bcr/abl chimeric protein-tyrosine kinase which has been found in many CML cases.

This DOK2 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 380-412 amino acids from the C-terminal region of human DOK2.

Store at 4˚ C for three months and -20˚ C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
