    Protocol

    Specificity / Sensitivity

    Phospho-c-Kit (Tyr823) Antibody recognizes endogenous levels of c-Kit protein only when phosphorylated at Tyr823. This antibody also recognizes a hSCF-induced, non-specific band at 95 kDa from a protein of unknown identity.

    Species Reactivity:

    Human

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr823 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).

    Tyr823 is located in the activation loop of the c-Kit kinase domain (8). Phosphorylation of c-Kit at Tyr823 is ligand-induced and has been shown to be important for cell survival and proliferation (9).
