SCF can exist both as a transmembrane protein and a soluble protein. This cytokine plays an important role in hematopoiesis (formation of blood cells), spermatogenesis, and melanogenesis. The gene encoding stem cell factor (SCF) is found on the Sl locus in mice and on chromosome 12q22-12q24 in humans. The soluble and transmembrane forms of the protein are formed by alternative splicing of the same RNA transcript,
