Automated description from the Alliance of Genome Resources (Release 7.4.0)

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).
