Protein attributes

Sequence length	390 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. Inhibits Wnt signaling By similarity.
Catalytic activity	2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H2O = ribonucleoside diphosphate + thioredoxin.
Cofactor	Binds 2 iron ions per subunit.
Pathway	Genetic information processing; DNA replication.
Subunit structure	Heterodimer of a large and a small subunit.
Subcellular location	Cytoplasm.
Post-translational modification	Phosphorylation on Ser-20 relieves the inhibitory effect on Wnt signaling By similarity.
Miscellaneous	Two distinct regulatory sites have been defined: the specificity site, which controls substrate specificity, and the activity site which regulates overall catalytic activity. A substrate-binding catalytic site, located on M1, is formed only in the presence of the second subunit M2.
Sequence similarities	Belongs to the ribonucleoside diphosphate reductase small chain family.
