Proto-oncogene c-KIT is the gene encoding the receptor tyrosine kinase protein known as tyrosine-protein kinase KIT, CD117 (cluster of differentiation 117) or mast/stem cell growth factor receptor (SCFR). Altered forms of this receptor may be associated with some types of cancer. KIT is a receptor tyrosine kinase type III, which binds to stem cell factor, also known as "steel factor" or "c-kit ligand" and expressed on the surface of hematopoietic stem cells as well as other cell types. When this receptor binds to stem cell factor (SCF) it forms a dimer that activates its intrinsic tyrosine kinase activity, that in turn phosphorylates and activates signal transduction molecules that propagate the signal in the cell. After activation, the receptor is ubiquitinated to mark it for transport to a lysosome and eventual destruction. Signaling through KIT plays a role in cell survival, proliferation, and differentiation. For instance, KIT signaling is required for melanocyte survival, and it is also involved in haematopoiesis and gametogenesis.
IF shows positive staining in paraffin-embedded human gastrointestinal stromal tumor. Anti- CD117 (Alexa Fluor® 594 Conjugate) antibody was used at 1/200 dilution (Red) and incubated overnight at 4°C. Counterstained with DAPI (Blue). Heat mediated antigen retrieval with EDTA buffer pH9.0 was performed before commencing with IF staining protocol.
