    Summary
    Enables ribonucleoside-diphosphate reductase activity, thioredoxin disulfide as acceptor. Involved in mitochondrial DNA replication and positive regulation of G0 to G1 transition. Acts upstream of or within several processes, including DNA repair; negative regulation of intrinsic apoptotic signaling pathway by p53 class mediator; and nucleoside phosphate metabolic process. Predicted to be located in nucleoplasm. Predicted to be part of ribonucleoside-diphosphate reductase complex. Predicted to be active in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 5; mitochondrial DNA depletion syndrome 8a; and mitochondrial DNA depletion syndrome 8b. Orthologous to human RRM2B (ribonucleotide reductase regulatory TP53 inducible subunit M2B). [provided by Alliance of Genome Resources, Dec 2024]

    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.
