Previous studies have shown that GATA3 function in T cell development is regulated by multiple signaling pathways and that the Notch nuclear effector, RBP-J, binds specifically to the Gata3 promoter. We previously identified a T cell?specific Gata3 enhancer (Tce1) lying 280 kb downstream from the structural gene and demonstrated in transgenic mice that Tce1 promoted T lymphocyte?specific transcription of reporter genes throughout T cell development; however, it was not clear if Tce1 is required for Gata3 transcription in vivo. Here, we determined that the canonical Gata3 promoter is insufficient for Gata3 transcriptional activation in T cells in vivo, precluding the possibility that promoter binding by a host of previously implicated transcription factors alone is responsible for Gata3 expression in T cells. Instead, we demonstrated that multiple lineage-affiliated transcription factors bind to Tce1 and that this enhancer confers T lymphocyte?specific Gata3 activation in vivo, as targeted deletion of Tce1 in a mouse model abrogated critical functions of this T cell?regulatory element. Together, our data show that Tce1 is both necessary and sufficient for critical aspects of Gata3 T cell?specific transcriptional activity.}, pages = {865--878}, title = {Lineage-affiliated transcription factors bind the Gata3 Tce1 enhancer to mediate lineage-specific programs}, volume = {126}, year = {2016}, yomi = {ミズノ, セイヤ and オオイシ, ヒサシ and タカハシ, サトル} }
