Homo sapiens

Also known as P53R2; RCDFRD; MTDPS8A; MTDPS8B

Gene ID: 50484 | Gene type: protein coding

About RRM2B

Cytogenetic location: 8q22.3 Genomic coordinates (GRCh38): 8:102,204,501-102,238,961 (from NCBI)

This gene has 10 transcripts (splice variants), 203 orthologues, 1 paralogue and is associated with 9 phenotypes. Ubiquitous expression in thyroid (RPKM 25.9), adrenal (RPKM 13.2) and 25 other tissues.

Summary

This gene encodes the small subunit of a p53-inducible ribonucleotide reductase. This heterotetrameric Enzyme catalyzes the conversion of ribonucleoside diphosphates to deoxyribonucleoside diphosphates. The product of this reaction is necessary for DNA synthesis. Mutations in this gene have been associated with autosomal recessive mitochondrial DNA depletion syndrome, autosomal dominant progressive external ophthalmoplegia-5, and mitochondrial neurogastrointestinal encephalopathy. Alternatively spliced transcript variants have been described.[provided by RefSeq, Feb 2010]
