Entrez Gene Summary for RRM2 Gene

  • This gene encodes one of two non-identical subunits for ribonucleotide reductase. This reductase catalyzes the formation of deoxyribonucleotides from ribonucleotides. Synthesis of the encoded protein (M2) is regulated in a cell-cycle dependent fashion. Transcription from this gene can initiate from alternative promoters, which results in two isoforms that differ in the lengths of their N-termini. Related pseudogenes have been identified on chromosomes 1 and X. [provided by RefSeq, Sep 2009]

GeneCards Summary for RRM2 Gene

RRM2 (Ribonucleotide Reductase M2) is a Protein Coding gene. Diseases associated with RRM2 include pancreatic cancer and pancreas adenocarcinoma. Among its related pathways are Cell Cycle, Mitotic and Cell Cycle, Mitotic. GO annotations related to this gene include transition metal ion binding and ribonucleoside-diphosphate reductase activity, thioredoxin disulfide as acceptor. An important paralog of this gene is RRM2B.
