Oligoribonuclease, mitochondrial

Known also as: RNA exonuclease 2 homolog, Small fragment nuclease

Known abbreviations: REXO2, SFN, SMFN, CGI-114


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 for cellular nucleotide recycling.


Homotetramer (Probable).


Isoform 1: Mitochondrion.
Isoform 2: Nucleus.



NCBI GI number(s): 224496106
