Target Information

KIT (c-KIT) is a proto-oncogene and a type 3 transmembrane receptor for MGF (mast cell growth factor, also known as stem cell factor).
KIT was first identified as the cellular homolog of the feline sarcoma viral oncogene v-kit.
KIT and its ligand regulate growth and activation of various hematopoietic and non-hematopoietic cells.
Mutations in KIT are associated with gastrointestinal stromal tumors, mast cell disease, acute myelogenous leukemia, and piebaldism.
Deregulation of the KIT receptor TK, especially by the D816V activation loop mutation, is a key therapeutic target in neoplastic mast cell growth.
c-Kit is expressed in hematopoietic stem cells, germ cells, mast cells, and gastrointestinal tract Cajal cells.
Upon binding of its ligand stem cell factor (SCF), c-Kit dimerizes, leading to receptor activation and autophosphorylation of tyrosine residues, including tyrosine 703.
This enables Grb2 docking and activation of the Ras/ERK signaling pathway.
SCF/c-Kit can also activate PI3K, PLC-γ, and JAK/STAT pathways.
c-Kit receptor activation is essential for hematopoiesis, stem cell maintenance, and gametogenesis.
