Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of movement of mRNA from the nucleus to the cytoplasm in the host organism.

Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of host mRNA transcription by directly inhibiting RNA polymerase II activity.

Enables the transfer of a purine nucleoside, a purine base covalently bonded to a ribose or deoxyribose sugar, from one side of a membrane to the other.

Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of mRNA processing in the host cell. mRNA processing is the conversion of a primary mRNA transcript into one or more mature mRNA(s) prior to translation into polypeptide.

Any viral process that interferes with the processing of mRNA in the host cell.

Any process in which a virus effects a change in the organization of chromatin in the host.

Any process in which a virus activates or increases the frequency, rate or extent of autophagy in the host.

Any process in which a symbiont organism increases the frequency, rate or extent of autophagy in the host cell. The host is defined as the larger of the organisms involved in a symbiotic interaction.

Any process in which a virus effect a change in the frequency, rate or extent of autophagy in the host.

Enables the transfer of galacturonate from one side of a membrane to the other. Galacturonate is the uronic acid formally derived from galactose by oxidation of the hydroxymethylene group at C-6 to a carboxyl group.

Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of autophagy in the host.

Any process in which a symbiont organism decreases the frequency, rate or extent of autophagy in the host cell. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The process in which an organism effects a change in host enzyme activity. The host is defined as the larger of the organisms involved in a symbiotic interaction.

The process in which a virus effects a change in host protein serine/threonine phosphatase activity.

Enables the transfer of L-idonate from one side of a membrane to the other. L-idonate is an aldonic acid derived from L-idose, an aldohexose which is epimeric with D-glucose.

Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of host cytokine activity.

Any process in which a virus stops, prevents, or reduces the frequency, rate or extent of the functional activity of a host interferon receptor.

Enables the directed movement of acriflavin from one side of a membrane to the other. Acriflavin is a fluorescent dye used as a local antiseptic and also as a biological stain. It intercalates into nucleic acids thereby inhibiting bacterial and viral replication.
