BP

GO:0006383

transcription from RNA polymerase III promoter

The synthesis of RNA from a DNA template by RNA polymerase III, originating at an RNAP III promoter.

GO:0032481

positive regulation of type I interferon production

Any process that activates or increases the frequency, rate, or extent of type I interferon production. Type I interferons include the interferon-alpha, beta, delta, episilon, zeta, kappa, tau, and omega gene families.

TAS

BP

GO:0032728

positive regulation of interferon-beta production

Any process that activates or increases the frequency, rate, or extent of interferon-beta production.

IMP

BP

GO:0045087

innate immune response

Innate immune responses are defense responses mediated by germline encoded components that directly recognize components of potential pathogens.

IEA

BP

GO:0045089

positive regulation of innate immune response

Any process that activates or increases the frequency, rate or extent of the innate immune response, the organism's first line of defense against infection.

IMP

BP

GO:0051607

defense response to virus

Reactions triggered in response to the presence of a virus that act to protect the cell or organism.

IEA

CC

GO:0005654

nucleoplasm

That part of the nuclear content other than the chromosomes or the nucleolus.

TAS

GO:0005666

DNA-directed RNA polymerase III complex

RNA polymerase III, one of three nuclear DNA-directed RNA polymerases found in all eukaryotes, is a multisubunit complex; typically it produces 5S rRNA, tRNAs and some of the small nuclear RNAs. Two large subunits comprise the most conserved portion including the catalytic site and share similarity with other eukaryotic and bacterial multisubunit RNA polymerases. The remainder of the complex is composed of smaller subunits (generally ten or more), some of which are also found in RNA polymerase I and others of which are also found in RNA polymerases I and II. Although the core is competent to mediate ribonucleic acid synthesis, it requires additional factors to select the appropriate template.

IDA

CC

GO:0005829

cytosol

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

TAS

MF

GO:0001056

RNA polymerase III activity

Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template that contains an RNA polymerase III specific promoter to direct initiation and catalyses DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.

IBA

MF

GO:0003677

DNA binding

Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).

IEA

MF

GO:0032549

ribonucleoside binding

Interacting selectively and non-covalently with a ribonucleoside, a compound consisting of a purine or pyrimidine nitrogenous base linked to ribose.

IEA

MF

GO:0046872

metal ion binding

Interacting selectively and non-covalently with any metal ion.
