RRM2

Ribonucleoside-diphosphate reductase subunit M2, also known as ribonucleotide reductase small subunit, is an is_associated_with::enzyme that in humans is encoded by the RRM2 is_associated_with::gene.

Function
This gene encodes one of two non-identical subunits for is_associated_with::ribonucleotide reductase. This reductase catalyzes the formation of deoxyribonucleotides from ribonucleotides. Synthesis of the encoded protein (M2) is regulated in a cell-cycle dependent fashion. Transcription from this gene can initiate from alternative promoters, which results in two isoforms that differ in the lengths of their N-termini.
