Mitochondrial transcription: how does it end?

Transcription. Jan-Feb 2011;2(1):32-6. doi: 10.4161/trns.2.1.14006.


The structure of the mitochondrial transcription termination factor (MTERF1) provides novel insight into the mechanism of binding, recognition of the termination sequence and the conformational changes involved in mediating termination. Besides its functional implications, this structure provides a framework to understand the consequences of numerous diseases associated with mitochondrial DNA mutations.

Keywords: MTERF; POLRMT; base-flipping; gene expression; mitochondria; mitochondrial transcription termination; polarity.
