Target Details

Target: LIF (Leukemia Inhibitory Factor (LIF))

Alternative Name: Lif

Background:

Synonyms: Differentiation-stimulating factor (D factor), Leukocyte Inhibitory Factor

Background: Mouse Leukemia Inhibitory Factor (LIF) is member of the IL-6 family and is made by a variety of tissues. LIF signals through receptors gp190 (LIFR) and gp130 to activate STAT3 which ultimately promotes mouse embryonic stem cell self-renewal and pluripotency of long term cultures. This activity is similar to that attributed to FGF-basic (FGF-2) for human embryonic stem cells. Recombinant mouse LIF is a non-glycosylated protein, containing 181 amino acids, with a molecular weight of 20 kDa.
