Entrez ID 25996
Gene name RNA exonuclease 2
Gene symbol REXO2
Synonyms (NCBI Gene)
CGI-114REX2RFNSFN
Chromosome 11
Chromosome location 11q23.2
Summary 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 degradatio
