This is an unusual zinc-finger family, and is represented by fingers 5-7 of Nab2. Nab2 ZnF5-7 are zinc-fingers of the type C-x8-C-x5-C-x3-H. Nab2 ZnFs function in the generation of export-competent mRNPs. Mab2 is a conserved polyadenosine-RNA-binding Zn finger protein required for both mRNA export and polyadenylation regulation and becomes attached to the mRNP after splicing and during or immediately after polyadenylation. The three ZnFs, 5-7, have almost identical folds and, most unusually, associate with one another to form a single coherent structural unit. ZnF5-7 bind to eight consecutive adenines, and chemical shift perturbations identify residues on each finger that interact with RNA [1].

This domain is found in Zinc finger CCCH-type antiviral protein 1 from Rattus norvegicus (Zc3hav1, also known as ZAP), which inhibits the replication of viruses by recruiting the cellular RNA degradation machineries to degrade the viral mRNAs. This protein has four zinc-finger motifs that are located at the four corners of a twisted rectangle in the bottom layer of the structure [4].
