Protein Structure
UniProt Annotation
Function Plays a pivotal role in cell survival by repairing damaged DNA in a p53/TP53-dependent manner. Supplies deoxyribonucleotides for DNA repair in cells arrested at G1 or G2. Contains an iron-tyrosyl free radical center required for catalysis. Forms an active ribonucleotide reductase (RNR) complex with RRM1 which is expressed both in resting and proliferating cells in response to DNA damage. {ECO:0000269PubMed:11517226, ECO:0000269PubMed:12858174}.
Subcellular Localization Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}. Note=Translocates from cytoplasm to nucleus in response to DNA damage. {ECO:0000250}.
