A point mutation in the catalytic domain of c-kit induces growth factor independence, tumorigenicity, and differentiation of mast cells

Abstract excerpt

The murine W and Steel loci encode the Kit receptor tyrosine kinase and its ligand, Steel factor, respectively. Loss of function mutations at either the W or Sl loci lead to a variety of pleiotropic developmental defects, including mast cell deficiency and severe macrocytic anemia. In addition to these loss-of-function mutations, gain-of-function mutations in c-kit, leading to constitutive activation of the Kit...
