Background Information

Ribonucleoside-diphosphate reductase large subunit (RRM1) is the main enzyme for de novo deoxyribonucleotide 

synthesis necessary for DNA synthesis during the cell cycle as well as during DNA repair.


What is the molecular weight of RRM1?

The molecular weight of RRM1 is 90 kDa. RRM1 is a part of ribonucleotide reductase (RNR), which is composed 

of two large RRM1 and two small RRM2 subunits in S phase and two large RRM1 and two alternative small p53R2 

subunits in non-dividing quiescent cells (PMID: 17416930).


What is the subcellular localization of RRM1?

RRM1 localizes to the cytoplasm, where it is responsible for dNTP production, forming a complex with RRM2. 

However, RRM1 can be recruited to DNA damage sites in the nucleus via interaction with Tip60 (PMID: 20159953).


What is the tissue expression pattern of RRM1?

RRM1 is ubiquitously expressed.


How is RRM1 expression regulated during the cell cycle and upon DNA damage?

Rrm1 gene expression levels depend on the cell cycle, and the highest mRNA levels are observed in S phase. 

However, RRM1 protein levels are constant throughout the cell cycle due to long protein half-life, contrary to 

RRM2, which is actively degraded after cell exit from S phase. During DNA damage, e.g., induced with genotoxins 

or UV light, expression of RRM1 and RRM2/p53R2 is upregulated (PMID: 1551913 and 8798592).
