Ribonucleotide reductase M2

RRM2, R-2, RR2, ribonucleotide reductase M2
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] (from NCBI)

Investigation of some DNA repair genes association in non small cell lung cancer.
Yaylim et al., İstanbul, Turkey. In Cell Mol Biol (noisy-le-grand), 2014
Ribonucleoside-diphosphate reductase subunit M2, also known as ribonucleotide reductase small subunit, is an enzyme that in humans is encoded by the RRM2 gene and also Ribonucleoside-diphosphate reductase large subunit is an enzyme that in humans is encoded by the RRM1 gene.
Inferior vena cava filters and postoperative outcomes in patients undergoing bariatric surgery: a meta-analysis.
Review
Cardiovascular Meta-analysis Research Group et al., Lima, Peru. In Surg Obes Relat Dis, 2014
Use of IVC filters was associated with an approximately 3-fold higher risk of DVT and death that was nominally significant for the former outcome, but not the latter (RR2.81,95%CI
Cyclin F-mediated degradation of ribonucleotide reductase M2 controls genome integrity and DNA repair.
Impact
GeneRIF
Pagano et al., New York City, United States. In Cell, 2012
After DNA damage, cyclin F is downregulated in an ATR-dependent manner to allow accumulation of RRM2. Defective elimination of cyclin F delays DNA repair and sensitizes cells to DNA damage, a phenotype that is reverted by expressing a nondegradable RRM2 mutant.
Progesterone and DNA damage encourage uterine cell proliferation and decidualization through up-regulating ribonucleotide reductase 2 expression during early pregnancy in mice.
GeneRIF
Yang et al., Shantou, China. In J Biol Chem, 2012
Data suggest that RRM2 may be an important effector of progesterone signaling to induce cell proliferation and decidualization in uterus.
Megalocytiviruses.
Review
Nakajima et al., Japan. In Viruses, 2012
Megalocytiviruses contain only the RR-2 gene, which is of eukaryotic origin; whereas the other genera encode both the RR-1 and RR-2 genes which are thought to originate from Rickettsia-like α-proteobacteria.
Regulation of urokinase expression at the posttranscription level by lung epithelial cells.
GeneRIF
Shetty et al., Tyler, United States. In Biochemistry, 2012
Recombinant RRM2 translocates from the cytoplasm to the nucleus in a time-dependent manner, leading to stabilization of urokinase mRNA. Overexpression of RRM2 inhibits urokinase protein and mRNA expression through destabilization of uPA mRNA.

Thus, genetic variation in key genes in the ara-C metabolic pathway--specifically, deoxycytidine kinase (a rate-limiting activating enzyme), 5 nucleotidase, cytidine deaminase and deoxycytidylate deaminase (all three are inactivating enzymes), human equilibrative nucleoside transporter (ara-C uptake transporter) and ribonucleotide reductase (RRM1 and RRM2--enzymes regulating intracellular deoxycytidine triphosphate pools)--form the molecular basis of the interpatient variability observed in intracellular ara-CTP concentrations and response to ara-C.
