p72 DEAD box RNA helicase is required for optimal function of the zinc-finger antiviral protein.
The zinc-finger antiviral protein (ZAP) specifically inhibits the replication of many viruses by preventing the accumulation of viral mRNAs in the cytoplasm. ZAP directly binds to the viral mRNAs and recruits the RNA exosome to degrade the target RNA. In the present study, we identified the p72 DEAD box RNA helicase, but not the highly similar RNA helicase p68, as a ZAP-interacting protein. The...
متن کاملZinc-Finger Antiviral Protein Inhibits XMRV Infection
BACKGROUND The zinc-finger antiviral protein (ZAP) is a host factor that specifically inhibits the replication of certain viruses, including Moloney murine leukemia virus (MoMLV), HIV-1, and certain alphaviruses and filoviruses. ZAP binds to specific viral mRNAs and recruits cellular mRNA degradation machinery to degrade the target RNA. The common features of ZAP-responsive RNA sequences remain...
متن کاملExpression of the zinc-finger antiviral protein inhibits alphavirus replication.
The rat zinc-finger antiviral protein (ZAP) was recently identified as a host protein conferring resistance to retroviral infection. We analyzed ZAP's ability to inhibit viruses from other families and found that ZAP potently inhibits the replication of multiple members of the Alphavirus genus within the Togaviridae, including Sindbis virus, Semliki Forest virus, Ross River virus, and Venezuela...
متن کاملZinc finger protein Loz1 is required for zinc-responsive regulation of gene expression in fission yeast.
In Schizosaccharomyces pombe, alcohol dehydrogenase 1 (Adh1) is an abundant zinc-requiring enzyme that catalyses the conversion of acetaldehyde to ethanol during fermentation. In a zinc-replete cell, adh1 is highly expressed. However, in zinc-limited cells, adh1 gene expression is repressed, and cells induce the expression of an alternative alcohol dehydrogenase encoded by the adh4 gene. In our...
متن کاملZinc finger protein Zfp335 is required for the formation of the naïve T cell compartment
The generation of naïve T lymphocytes is critical for immune function yet the mechanisms governing their maturation remain incompletely understood. We have identified a mouse mutant, bloto, that harbors a hypomorphic mutation in the zinc finger protein Zfp335. Zfp335(bloto/bloto) mice exhibit a naïve T cell deficiency due to an intrinsic developmental defect that begins to manifest in the thymu...
