Summary
Predicted to enable ATP:3'-cytidine-cytidine-tRNA adenylyltransferase activity; tRNA binding activity; and tRNA nucleotidyltransferase activity. Predicted to be involved in mitochondrial tRNA 3'-end processing and tRNA 3'-terminal CCA addition. Predicted to act upstream of or within tRNA processing. Located in mitochondrion. Human ortholog(s) of this gene implicated in sideroblastic anemia with B-cell immunodeficiency, periodic fevers, and developmental delay. Orthologous to human TRNT1 (tRNA nucleotidyl transferase 1).

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.
