... The purification of complete eukaryotic Ago protein was difficult so experiments were performed with their prokaryotic homolog which revealed that it has a structure similar to RNase H ribonuclease (19). The ago protein was found to be comprised of 4 major domains: N- terminal, PAZ domain, Middle an ...
