生化／生理作用
DIF-1 (differentiation-inducing factor-1) is isolated from a Dictyostelium slime mold, and is used to inhibit proliferation/promote differentiation in various cell lines.
DIF-1 is a cell differentiation inducing factor.
Differentiation-inducing factor-1 (DIF-1) blocks the migration and invasion of cells and decreases the expression of matrix metalloproteinase-2. It prevents the proliferation of cells using glycogen synthase kinase-3 (GSK-3)-dependent mechanism. DIF-1 is more active when compared to DIF-2 in promoting stalk cell differentiation under submerged assay conditions.

Differentiation-inducing factor 1 (DIF-1) is a polyketide-derived morphogen which drives stalk cell formation in the developmental cycle of Dictyostelium discoideum. Previous experiments demonstrated that the biosynthetic pathway proceeds via dichlorination of the precursor molecule THPH, but the enzyme responsible for
Glutathione S-transferase 4 is a putative DIF-binding protein that regulates the size of fruiting bodies in Dictyostelium discoideum.

Exposure of monolayer Dictyostelium cells to the signalling polyketide DIF-1 causes DimB, a bZIPtranscription factor, to accumulate in the nucleus where it induces prestalk gene expression. Here we analyse DimB signalling during normal development. In slugs DimB is specifically nuclear

The Dictyostelium transcription factor STATc is tyrosine phosphorylated and accumulates in the nucleus when cells are exposed either to hyper-osmotic stress or to the prestalk-inducing polyketide DIF-1. In the case of stress STAT activation is mediated by regulated dephosphorylation; whereby

The differentiation-inducing factor-1 (DIF-1) is a lipophilic signal molecule (chlorinated alkylphenone) that induces stalk cell differentiation in the cellular slime mold Dictyostelium discoideum. In addition, DIF-1 and its derivatives have been shown to possess anti-leukemic activity and glucose consumption-promoting activity
