B PF13008 zf-Paramyx-P Zinc-binding domain of Paramyxoviridae V protein Domain The Paramyxoviridae, which include such respiroviruses as para-influenzae and measles, produce phosphoproteins - protein P - that are integral to the polymerase transcription-replication complex. Protein P consists of two functionally distinct moieties, an N-terminal PNT, and a C-terminal PCT [1]. The P gene region transcribes proteins from all three ORFs, and the V protein consists of the PNT moiety and a more C-terminal 2-zinc-binding domain. This conserved region consists of the two-zinc-binding section sandwiched between beta sheets 6 and 7 of the overall V protein. It is the binding of this core domain of V protein with the DDB1 protein (part of the ubiquitin-ligase complex) of eukaryotes which represents the key element of the virus-host protein interaction [3]. In the Henipavirus family which includes Nipah and Hendra viruses, the V protein is able to block IFN (interferon) signalling by preventing IFN-induced STAT phosphorylation and nuclear translocation [2]. The P gene of morbillivirus is co-transcriptionally edited leading to a V protein being produced. PFAM PF13008
