This antibody also recognizes a hSCF-induced, non-specific band at 95 kDa from a protein of unknown identity.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nPolyclonal 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.\n\u003cb\u003eBackground\u003c\/b\u003e\nc-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 PLCÎ³, 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 and (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).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nC-Kit; c-Kit protooncogene; CD117; ckit; KIT; KIT proto-oncogene, receptor tyrosine kinase; Mast\/stem cell growth factor receptor; Mast\/stem cell growth factor receptor Kit; MASTC; p145 c-kit; PBT; Piebald trait protein; Proto-oncogene c-Kit; proto-oncogene tyrosine-protein kinase Kit; SCFR; soluble KIT variant 1; Tyrosine-protein kinase Kit; v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog; v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene-like protein\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 145\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799605924009,"sku":"48347S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-48347s","provider":"Iright","version":"1.0","type":"link"}
