Ribonucleoside-diphosphate reductase subunit M2 (RRM2; 389 aa, 45 kDa) also known as ribonucleotide reductase subunit R2 (RNR-R2), is a rate-limiting subunit of an enzyme that catalyzes the formation of deoxyribonucleotides from ribonucleotides. Deoxyribonucleotides in turn are used in the synthesis of DNA. The reaction catalyzed by RNR is strictly conserved in all living organisms. Furthermore RNR plays a critical role in regulating the total rate of DNA synthesis so that DNA to cell mass is maintained at a constant ratio during cell division and DNA repair.

Fig.1 Western blot analysis of RRM2 (45 kDa) in the whole cell extracts of MCF7 (Breast cancer cell line). Extract (,20mg). Antibody was 1,000-fold diluted. RRM2 is phosphorylated at three residues and the multiple bands correspond to them.

Fig2. Western blot analysis of RRM2 protein in the whole cell extract of Hela. Extract (20 ug). Anti-RRM2 antibody was used at 1/2000 dilution.

Fig. 3 Western blot analysis of RRM2 protein in mitotic extract of Xenopus egg. Anti-RRM2 antibody was used at 1/1,000 dilution


Fig.4 Immunofluorescence staining of RRM2 protein in MCF cells with anti-RRM2 antibody. MCF7 cells were fixed with 4%PFA and permeabilized with 0.25% TritonX 100 and reacted with anti-RRM2 antibody at 1/100 dilution. As the second antibody, anti-rabbit IgG antibody conjugated with Alexa Fluor 488 (Abcam) was used at 1/1,000 dilution. DNA was stained with 1.0μg/mL DAPI in TBS.
