{Reference Type}: Journal Article {Title}: Friedreich's ataxia--a case of aberrant transcription termination? {Author}: Butler JS;Napierala M; {Journal}: Transcription {Volume}: 6 {Issue}: 2 {Year}: 2015 暂无{DOI}: 10.1080/21541264.2015.1026538 {Abstract}: Reduced expression of the mitochondrial protein Frataxin (FXN) is the underlying cause of Friedreich's ataxia. We propose a model of premature termination of FXN transcription induced by pathogenic expanded GAA repeats that links R-loop structures, antisense transcription, and heterochromatin formation as a novel mechanism of transcriptional repression in Friedreich's ataxia.
