Highlights? GRSF1 (G-rich sequence binding factor 1) is a mitochondrial RNA-binding protein ? GRSF1 localizes to granules containing newly synthesized RNA in close proximity to mitochondrial nucleoids ? GRSF1 specifically binds one mRNA and two long noncoding RNAs transcribed from contiguous genes on the light strand of mtDNA ? Loss of GRSF1 leads to misloading of RNAs onto the mitochondrial ribosome and a specific translation defect 相似文献
