Name Interferon-stimulated gene 20 kDa protein
Description Not Available
Synonyms
  1. Estrogen-regulated transcript 45 protein
  2. Promyelocytic leukemia nuclear body-associated protein ISG20
Gene Name ISG20
Protein Type Enzyme
Biological Properties
General Function Involved in exonuclease activity
Specific Function Exonuclease with specificity for single-stranded RNA and, to a lesser extent for DNA. Degrades RNA at a rate that is approximately 35-fold higher than its rate for single-stranded DNA. Involved in the antiviral function of IFN against RNA viruses
