It contains two conserved histidine residues and four conserved cysteine residues in a CHC3H motif. It can bind divalent transition metals, with a preference for Zn2+. ZNFX1 is an RNA-binding protein that initiates the antiviral response and is required to restrict the replication of RNA viruses [1,2]. RNF213 is a giant E3 ubiquitin ligase that can catalyse ubiquitination of both proteins and lipids, which is involved in various processes, such as lipid metabolism, angiogenesis and cell-autonomous immunity. It functions as a key immune sensor by catalysing ubiquitination of the lipid A moiety of bacterial LPS via its RZ-type zinc-finger and restricts the proliferation of cytosolic bacteria [3,4]. RNF213 is a major susceptibility factor of Moyamoya disease [5].

Many proteins containing a RING finger play a key role in the ubiquitination pathway [2].
