Target

  • Function

    Regulator of post-transcriptional mitochondrial gene expression, required for assembly of the mitochondrial ribosome and for recruitment of mRNA and lncRNA. Binds RNAs containing the 14 base G-rich element. Preferentially binds RNAs transcribed from three contiguous genes on the light strand of mtDNA, the ND6 mRNA, and the long non-coding RNAs for MT-CYB and MT-ND5, each of which contains multiple consensus binding sequences.
  • Sequence similarities

    Contains 3 RRM (RNA recognition motif) domains.
  • Cellular localization

    Cytoplasm. Mitochondrion matrix > mitochondrion nucleoid. Forms granules that colocalize with foci of newly synthesized mtRNA next to mitochondrial nucleoids.
