Article Title: | MTERF4 regulates translation by targeting the methyltransferase NSUN4 to the mammalian mitochondrial ribosome |
Abstract: | Precise control of mitochondrial DNA gene expression is critical for regulation of oxidative phosphorylation capacity in mammals. The MTERF protein family plays a key role in this process, and its members have been implicated in regulation of transcription initiation and site-specific transcription termination. We now demonstrate that a member of this family, MTERF4, directly controls mitochondrial ribosomal biogenesis and translation. MTERF4 forms a stoichiometric complex with the ribosomal RNA methyltransferase NSUN4 and is necessary for recruitment of this factor to the large ribosomal subunit. Loss of MTERF4 leads to defective ribosomal assembly and a drastic reduction in translation. Our results thus show that MTERF4 is an important regulator of translation in mammalian mitochondria. © 2011 Elsevier Inc. |
