argonaute proteins

Quick Reference

Proteins (eukaryotic translation initiation factors 2C1–4, argonaute 1–4, AGO1–4, ~857 aa) that are concentrated in GW bodies and are key components of RNA-induced silencing complexes (RISCs) where they bind single-stranded small interfering RNA (siRNA) and microRNA. They are also important in peptide chain initiation. The argonaute proteins have slicer activity and contain N-terminal PAZ (PIWI/Argonaute/Zwille) domains and C-terminal piwi domains.
