Summaries for REXO2 Gene

Entrez Gene Summary for REXO2 Gene

  • This gene encodes a 3'-to-5' exonuclease specific for small (primarily 5 nucleotides or less in length) single-stranded RNA and DNA oligomers. This protein may have a role in DNA repair, replication, and recombination, and in RNA processing and degradation. It may also be involved in resistance of human cells to UV-C-induced cell death through its role in the DNA repair process. [provided by RefSeq, Nov 2011]

GeneCards Summary for REXO2 Gene

REXO2 (RNA Exonuclease 2) is a Protein Coding gene. Among its related pathways are Ribosome biogenesis in eukaryotes. GO annotations related to this gene include nucleic acid binding and 3-5-exoribonuclease activity.

UniProtKB/Swiss-Prot for REXO2 Gene

  • 3-to-5 exoribonuclease specific for small oligoribonucleotides. Active on small (primarily </=5 nucleotides in length) single-stranded RNA and DNA oligomers. May have a role in cellular nucleotide recycling.
