引用 | ジャーナル: Nature / 年: 2023 タイトル: FOXP3 recognizes microsatellites and bridges DNA through multimerization. 著者: Wenxiang Zhang / Fangwei Leng / Xi Wang / Ricardo N Ramirez / Jinseok Park / Christophe Benoist / Sun Hur / 要旨: FOXP3 is a transcription factor that is essential for the development of regulatory T cells, a branch of T cells that suppress excessive inflammation and autoimmunity. However, the molecular ...FOXP3 is a transcription factor that is essential for the development of regulatory T cells, a branch of T cells that suppress excessive inflammation and autoimmunity. However, the molecular mechanisms of FOXP3 remain unclear. Here we here show that FOXP3 uses the forkhead domain-a DNA-binding domain that is commonly thought to function as a monomer or dimer-to form a higher-order multimer after binding to TG repeat microsatellites. The cryo-electron microscopy structure of FOXP3 in a complex with TG repeats reveals a ladder-like architecture, whereby two double-stranded DNA molecules form the two 'side rails' bridged by five pairs of FOXP3 molecules, with each pair forming a 'rung'. Each FOXP3 subunit occupies TGTTTGT within the repeats in a manner that is indistinguishable from that of FOXP3 bound to the forkhead consensus motif (TGTTTAC). Mutations in the intra-rung interface impair TG repeat recognition, DNA bridging and the cellular functions of FOXP3, all without affecting binding to the forkhead consensus motif. FOXP3 can tolerate variable inter-rung spacings, explaining its broad specificity for TG-repeat-like sequences in vivo and in vitro. Both FOXP3 orthologues and paralogues show similar TG repeat recognition and DNA bridging. These findings therefore reveal a mode of DNA recognition that involves transcription factor homomultimerization and DNA bridging, and further implicates microsatellites in transcriptional regulation and diseases. | |||||||||
