Protein

Ribonucleoside-diphosphate reductase subunit M2 B

Gene
RRM2B
Organism
Pongo abelii (Sumatran orangutan) (Pongo pygmaeus abelii)
Status
Reviewed - Annotation score: 4 out of 5 - Experimental evidence at transcript leveli

Functioni

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 By similarity.

Catalytic activityi

2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin.

Cofactori

Binds 2 iron ions per subunit By similarity.
