Reference Data

• RefSeq: NP_000890
• Locus ID: 4254
• UniProt ID: P21583
• Cytogenetics: 12q21.32
• Synonyms: KITL, Kit ligand, c-Kit ligand, Stem cell factor, Mast cell growth factor, MGF
• Summary: This gene encodes the ligand of the tyrosine-kinase receptor encoded by the KIT locus. This ligand is a pleiotropic factor that acts in utero in germ cell and neural cell development, and hematopoiesis, all believed to reflect a role in cell migration. In adults, it functions pleiotropically, while mostly noted for its continued requirement in hematopoiesis. Two transcript variants encoding different isoforms have been found for this gene.
