C-Kit (CD117) is an antibody that identifies the C-Kit protein.

Molecule Type and Chemical Structure

C-Kit belongs to the type III receptor tyrosine kinase (RTK) subfamily, whose members include platelet-derived growth factor receptors α and β (PDGFRα and PDGFRβ) (Roskoski 2005). All type III RTKs contain five immunoglobulin-like domains in their extracellular ligand-binding region followed by a single transmembrane domain and a cytoplasmic tyrosine kinase domain interrupted by a large kinase insert. The ligand of KIT is known as stem cell factor. C-Kit(the gene) is transcribed and ultimately translated into the KIT protein, a transmembrane receptor tyrosine...
