GO
GO:0003677 Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). GO:0006355 Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription. GO:0003700 A transcription regulator activity that modulates transcription of gene sets via selective and non-covalent binding to a specific double-stranded genomic DNA sequence (sometimes referred to as a motif) within a cis-regulatory region. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units, and include bacterial operons. GO:0000976 Binding to a specific sequence of DNA that is part of a regulatory region that controls transcription of that section of the DNA. The transcribed region might be described as a gene, cistron, or operon. GO:0055085 The process in which a solute is transported across a lipid bilayer, from one side of a membrane to the other.
