The <scene name='Argonaute/Ago2-paz/1'>Paz Domain</scene> is responsible for binding to the 3'-end overhangs of single-stranded RNAs and siRNA duplexes <ref name='ref3'>pmid 15152257</ref> and was shown to be essential for RISC activation <ref name='ref3'>pmid 22795694</ref>. <scene name='Argonaute/Ago2-paz-obfold/2'>The domain is composed of two subdomains:</scene> the first is similar to the OB fold, a well known nucleic acid binding fold; the second subdomain is composed of a beta-hairpin followed by an alpha-helix. The cleft in between these two subdomains appears to interact with the 3' ends of ssRNA <ref name='ref3'>pmid 14615801</ref>.
