Summary: Predicted to enable ribonucleoside-diphosphate reductase activity, thioredoxin disulfide as acceptor. Predicted to be involved in deoxyribonucleotide biosynthetic process. Predicted to be part of ribonucleoside-diphosphate reductase complex. Predicted to be active in cytosol. Is expressed in several structures, including CNS glial cell; embryonic/larval midgut primordium; ganglia; gut section; and head epidermis primordium. Human ortholog(s) of this gene implicated in autosomal dominant progressive external ophthalmoplegia with mitochondrial DNA deletions 5; mitochondrial DNA depletion syndrome 8a; mitochondrial DNA depletion syndrome 8b; and pancreatic cancer. Orthologous to several human genes including RRM2 (ribonucleotide reductase regulatory subunit M2). [provided by Alliance of Genome Resources, Dec 2024]
