EXO2 is a 3'-to-5' exonuclease specific for small (primarily 5 nucleotides or less in length) single-stranded RNA and DNA oligomers. RNA Exonuclease 2 (REXO2) takes part in DNA repair, replication, and recombination, and in RNA processing and degradation. EXO2 is involved in resistance of human cells to UV-C-induced cell death via its part in the DNA repair process.

REXO2 Human Recombinant produced in E. coli is a single polypeptide chain containing 235 amino acids (26-237) and having a molecular mass of 26.8kDa. REXO2 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Escherichia Coli.
