Possible Fer4-like domain in RNase L inhibitor, RLI
Possible metal-binding domain in endoribonuclease RNase L inhibitor. Found at the N-terminal end of RNase L inhibitor proteins, adjacent to the 4Fe-4S binding domain, fer4, pfam00037. Also often found adjacent to the DUF367 domain pfam04034 in uncharacterized proteins. The RNase L system plays a major role in the anti-viral and anti-proliferative activities of interferons, and could possibly play a more general role in the regulation of RNA stability in mammalian cells. Inhibitory activity requires concentration-dependent association of RLI with RNase L.
