    Protocol

    Specificity / Sensitivity

    Phospho-c-Kit (Tyr568/570) Antibody recognizes endogenous levels of c-Kit protein only when phosphorylated at Tyr568/570. This antibody also recognizes a hSCF-induced, non-specific band at 95 kDa from a protein of unknown identity.

    Species Reactivity:

    Human

    The antigen sequence used to produce this antibody shares 100% sequence homology with the species listed here, but reactivity has not been tested or confirmed to work by CST. Use of this product with these species is not covered under our Product Performance Guarantee.

    Species predicted to react based on 100% sequence homology:

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr568/570 of human c-Kit protein. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    c-Kit is a member of the subfamily of receptor tyrosine kinases that includes PDGF, CSF-1, and FLT3/flk-2 receptors (1,2). It plays a critical role in activation and growth in a number of cell types, including hematopoietic stem cells, mast cells, melanocytes, and germ cells (3). Upon binding with its stem cell factor (SCF) ligand, c-Kit undergoes dimerization/oligomerization and autophosphorylation. Activation of c-Kit results in the recruitment and tyrosine phosphorylation of downstream SH2-containing signaling components, including PLCγ, the p85 subunit of PI3 kinase, SHP2, and CrkL (4). Molecular lesions that impair the kinase activity of c-Kit are associated with a variety of developmental disorders (5), and mutations that constitutively activate c-Kit can lead to pathogenesis of mastocytosis and gastrointestinal stromal tumors (6). Tyr719 is located in the kinase insert region of the catalytic domain. c-Kit phosphorylated at Tyr719 binds to the p85 subunit of PI3 kinase in vitro and in vivo (7).

    Tyr568 and Tyr570 are located in the juxtamembrane region of c-Kit. The phosphorylation of c-Kit at these sites is ligand induced and provides a docking site for recruitment of several adaptors/kinases, including Src, Cbl, SHP-1, APS, LNK, and SOSC6. Depending on which adaptor is bound, the outcome can lead to either cell survival and proliferation or c-Kit ubiquitination and degradation (8-13).
