Zinc-finger antiviral protein (ZAP) is a host factor that specifically inhibits the replication of certain viruses, such as HIV-1, by targeting viral mRNA for degradation. N-terminal domain of ZAP is the major functional domain which contains four zinc-finger motifs. This entry represents the third zinc finger type CCCH [1].	Domain
