GO
GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. GO:0000160 A conserved series of molecular signals found in prokaryotes and eukaryotes; involves autophosphorylation of a histidine kinase and the transfer of the phosphate group to an aspartate that then acts as a phospho-donor to response regulator proteins. GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). GO:0005829 The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. GO:0032993 A macromolecular complex containing both protein and DNA molecules. GO:0000987 Binding to a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site, located in cis relative to the transcription start site (i.e., on the same strand of DNA) of a gene transcribed by some RNA polymerase. Cis-regulatory sites are often referred to as a sequence motifs, enhancers, or silencers.
