KIT, also known as c-KIT, SCFR (stem cell factor receptor), PBT (Piebald trait protein), and CD117, is a single pass type I transmembrane protein belonging to the receptor tyrosine kinase (RTK) family and the CSF-1/PDGF receptor subfamily.  KIT is a cellular homolog of the feline  sarcoma virus protein, v-Kit. Kit contains 5 immunoglobulin (Ig)-like C2-type domains in the extracellular domain (ECD) and 1 split tyrosine kinase domain in the cytoplasmic region. Alternative splicing of KIT generates a potentially secreted isoform corresponding to the first 4 Ig-like domains.  KIT may act as cell-surface receptor for the cytokine KITLG/SCF and play an essential role in the regulation of cell survival and proliferation, hematopoiesis, stem cell maintenance, gametogenesis, mast cell development, migration and function, and in melanogenesis. In response to KITLG/SCF, KIT can activate PI3K and AKT1 signaling pathways. Activated KIT also transmits signals via GRB2 and activation of RAS, RAF1 and the MAP kinases, MAPK1/ERK2 and/or MAPK3/ERK1. KIT promotes activation of STAT family members STAT1, STAT3, STAT5A and STAT5B. KIT signaling is modulated by protein phosphatases, and by rapid internalization and degradation of the receptor. Mutations in the KIT gene are associated with gastrointestinal stromal tumors (GIST), mast cell disease, acute myelogenous leukemia (AML), and piebaldism. KIT protects  vascular smooth muscle cells from apoptosis and assists in the recovery of cardiac function following myocardial infarction.
