Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.

    GO:0000978    RNA polymerase II proximal promoter sequence-specific DNA binding    Interacting selectively and non-covalently with a specific upstream regulatory DNA sequence (transcription factor recognition sequence or binding site) located in the proximal promoter of a gene transcribed by RNA polymerase II. The proximal promoter is in cis with and relatively close to the core promoter.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0001077    proximal promoter DNA-binding transcription activator activity, RNA polymerase II-specific    A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within a proximal promoter regulatory region of a RNA polymerase II-transcribed gene to activate or increase transcription.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0000436    carbon catabolite activation of transcription from RNA polymerase II promoter    Any process involving carbon catabolites that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0071169    establishment of protein localization to chromatin    The directed movement of a protein to a part of a chromosome that is organized into chromatin.
    GO:0061428    negative regulation of transcription from RNA polymerase II promoter in response to hypoxia    Any process that decreases the frequency, rate or extent of transcription from an RNA polymerase II promoter as a result of a hypoxia stimulus.
    GO:0043457    regulation of cellular respiration    Any process that modulates the frequency, rate or extent of cellular respiration, the enzymatic release of energy from organic compounds.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006366    transcription by RNA polymerase II    The synthesis of RNA from a DNA template by RNA polymerase II, originating at an RNA polymerase II promoter. Includes transcription of messenger RNA (mRNA) and certain small nuclear RNAs (snRNAs).
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
cellular component
    GO:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

    GO:0000981    DNA-binding transcription factor activity, RNA polymerase II-specific    A protein or a member of a complex that interacts selectively and non-covalently with a specific DNA sequence (sometimes referred to as a motif) within the regulatory region of a RNA polymerase II-transcribed gene to modulate transcription. Regulatory regions include promoters (proximal and distal) and enhancers. Genes are transcriptional units.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
