REX2, RNA exonuclease 2 homolog (S. cerevisiae), also known as REXO2, is an enzyme which in humans is encoded by the REXO2 gene.⁵⁶⁷

Function

Nucleases are components of DNA and RNA metabolism that carry out functions in DNA repair, replication, and recombination and in RNA processing and degradation. SFN is a homolog of Orn, a 3-prime-to-5-prime exoribonuclease of E. coli that attacks the free 3-prime hydroxyl group on single-stranded RNA, releasing 5-prime mono-nucleotides in a sequential manner.⁵
