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.

TAS

GO:0006386

termination of RNA polymerase III transcription

The process in which transcription by RNA polymerase III is terminated; Pol III has an intrinsic ability to terminate transcription upon incorporation of 4 to 6 contiguous U residues.

IBA

BP

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:0045087

innate immune response

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

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.

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.

GO:0005730

nucleolus

A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome.

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:0003676

nucleic acid binding

Interacting selectively and non-covalently with any nucleic acid.

IEA

MF

GO:0003899

DNA-directed RNA polymerase activity

Catalysis of the reaction: nucleoside triphosphate + RNA(n) = diphosphate + RNA(n+1). Utilizes a DNA template, i.e. the catalysis of DNA-template-directed extension of the 3'-end of an RNA strand by one nucleotide at a time. Can initiate a chain 'de novo'.

TAS

MF

GO:0008270

zinc ion binding

Interacting selectively and non-covalently with zinc (Zn) ions.
