Steel factor

Steel factor receptor interacts chemically with steel factor or stem cell factor to relay chemical messages.

The products of these two loci are now known to be the tyrosine kinase receptor Kit ( W ) and its ligand Steel factor ( Steel ).

CD117 is a receptor tyrosine kinase type III, which binds to stem cell factor (a substance that causes certain types of cells to grow), also known as "steel factor" or "c-kit ligand".
