Research Abstract

GATA3 is the master transcription factor for T helper 2 (Th2) cell differentiation and is critical for the expression of Th2 cytokines. Little is known, however, about the nature of the functional molecular complexes of GATA3. We identified a chromodomain-containing transcription factor, chromodomain helicase DNA binding protein 4 (Chd4) in the GATA3 complex present in Th2 cells. We found that Th2 cell differentiation is impaired in Chd4-knockdown cells and Chd4 binds to the Th2 cytokine gene loci in a GATA3-dependent manner. These results suggest that the GATA3-dependent recruitment of Chd4 at the Th2 cytokine gene loci is involved in the induction of Th2 cytokine expression.
