Summary: Predicted to enable 3'-5'-exoribonuclease activity; RNA binding activity; and polyribonucleotide nucleotidyltransferase activity. Involved in mitochondrial mRNA catabolic process; mitochondrion morphogenesis; and regulation of cellular respiration. Located in mitochondrial intermembrane space. Is expressed in central nervous system and sensory organ.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
