Target Information

KIT (c-KIT) is a proto-oncogene and a type 3 transmembrane receptor for mast cell growth factor (MGF, also known as stem cell factor). KIT was first identified as the cellular homolog of the feline sarcoma viral oncogene v-kit. Together with its ligand, KIT regulates growth and activation of various hemopoietic and non-hemopoietic cells.

Mutations in KIT are associated with gastrointestinal stromal tumors, mast cell disease, acute myelogenous leukemia, and piebaldism. Deregulation of the KIT receptor tyrosine kinase by the activation loop mutation D816V has become a focus in therapeutic strategies against neoplastic mast cell growth.

c-Kit is expressed in hematopoietic stem cells, germ cells, mast cells, and gastrointestinal tract Cajal cells. Upon binding of stem cell factor (SCF), c-Kit dimerizes, leading to receptor activation and autophosphorylation of tyrosine residues (including tyrosine 703). This enables docking of Grb2 and activation of the Ras/ERK signaling pathway. SCF/c-Kit also activates PI3K, PLC-γ, and JAK/STAT pathways, essential for hematopoiesis, stem cell maintenance, and gametogenesis.
