Fms-like tyrosine kinase 3 ligand is a hematopoietic cytokine structurally similar to stem cell factor (SCF) and colony stimulating factor 1 (CSF-1). Flt-3 ligand synergizes with other growth factors, such as interleukin-7 (IL-7) and CSFs, to promote proliferation and differentiation of early hematopoietic cells. In addition, Flt-3 ligand is involved in the commitment and expansion of dendritic cells as well as stimulating B cells, T cells, and NK cells. Both soluble form and membrane-bound forms of Flt-3 ligand are able to stimulate the cells expressing receptor tyrosine kinases Flt-3, transducing signals through the ERK and PI3K pathway. Flt-3 ligand is the only known ligand for Flt-3. Flt-3 and Flt-3 ligand have been implicated to participate in leukemogenesis, since the constitutively activated mutants of Flt-3 were found to be associated with the acute myeloid leukemia (AML).
Product Details
