InnateDB Annotation
KITLG is a PI3K-activating ligand that increases the secretion of IL6 and TNFA in LPS-stimulated mast cells, as well as the attenuating the production of IL1B. (Demonstrated in murine model)
InnateDB Annotation from Orthologs
[Mus musculus] Kitl is a PI3K-activating ligand that increases the secretion of Il6 and Tnfa in LPS-stimulated mast cells, as well as the attenuating the production of Il1b.
Entrez Gene
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.
