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 and (7). Tyr703 is also located in kinase insert of c-kit. Its phosphorylation provides a docking site for Grb2 binding (8). It was demonstrated that Tyr703 was constitutively phosphorylated in GIST tumor cells (9).\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\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46798068580521,"sku":"3073S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3073s","provider":"Iright","version":"1.0","type":"link"}
