NCIt definition : Human RRM1 wild-type allele is located in the vicinity of 11p15.5 and is approximately
44 kb in length. This allele, which encodes ribonucleoside-diphosphate reductase large
subunit protein, is involved in reduction of ribonucleotides to deoxyribonucleotide
precursors for DNA synthesis in dividing cells.;
NCIt note : Overexpression of the RR1 gene decreases the efficiency of several anti-cancer drugs
in patients undergoing chemotherapy. However, certain variant alleles of this gene
are associated with increased survival of lung cancer patients following tumor resection.;
