Planteome: Term Details for "sigma factor activity" (GO:0016987)

Term Information

Accession: GO:0016987
Name: sigma factor activity
Ontology: molecular_function
Synonyms: DNA-dependent RNA polymerase promoter selection factor, core DNA-dependent RNA polymerase binding promoter specificity activity, sigma transcription factor, bacterial sigma factor activity, plastid sigma factor activity, promoter selection factor activity
Alternate IDs: GO:0000996, GO:0001053
Definition: Sigma factors act as the promoter specificity subunit of eubacterial and plant plastid multisubunit RNA polymerases, whose core subunit composition is often described as alpha(2)-beta-beta-prime. Although sigma does not bind DNA on its own, when combined with the core to form the holoenzyme, the sigma factor binds specifically to promoter elements. The sigma subunit is released once elongation begins. Source: GOC:txnOH-2018
