Chain A,B,C,D   (TAT_EIAVC | P32544)
molecular function
    GO:0003723    RNA binding    Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
    GO:0003700    transcription factor activity, sequence-specific DNA binding    Interacting selectively and non-covalently with a specific DNA sequence in order to modulate transcription. The transcription factor may or may not also interact selectively with a protein or macromolecular complex.
biological process
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
cellular component
    GO:0044196    host cell nucleolus    A small, dense body one or more of which are present in the nucleus of eukaryotic host cells.
    GO:0042025    host cell nucleus    A membrane-bounded organelle as it is found in the host cell in which chromosomes are housed and replicated. The host is defined as the larger of the organisms involved in a symbiotic interaction.

Chain A,B,C,D   (CCNT1_HUMAN | O60563)
molecular function
    GO:0097322    7SK snRNA binding    Interacting selectively and non-covalently with a 7SK small nuclear RNA (7SK snRNA).
    GO:0003677    DNA binding    Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid).
    GO:0070063    RNA polymerase binding    Interacting selectively and non-covalently with an RNA polymerase molecule or complex.
    GO:0003682    chromatin binding    Interacting selectively and non-covalently with chromatin, the network of fibers of DNA, protein, and sometimes RNA, that make up the chromosomes of the eukaryotic nucleus during interphase.
    GO:0016538    cyclin-dependent protein serine/threonine kinase regulator activity    Modulates the activity of a cyclin-dependent protein serine/threonine kinase, enzymes of the protein kinase family that are regulated through association with cyclins and other proteins.
    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).
    GO:0004674    protein serine/threonine kinase activity    Catalysis of the reactions: ATP + protein serine = ADP + protein serine phosphate, and ATP + protein threonine = ADP + protein threonine phosphate.
    GO:0017069    snRNA binding    Interacting selectively and non-covalently with a small nuclear RNA (snRNA).
    GO:0044212    transcription regulatory region DNA binding    Interacting selectively and non-covalently with a DNA region that regulates the transcription of a region of DNA, which may be a gene, cistron, or operon. Binding may occur as a sequence specific interaction or as an interaction observed only once a factor has been recruited to the DNA by other factors.
biological process
    GO:0007049    cell cycle    The progression of biochemical and morphological phases and events that occur in a cell during successive cell replication or nuclear replication events. Canonically, the cell cycle comprises the replication and segregation of genetic material followed by the division of the cell, but in endocycles or syncytial cells nuclear replication or nuclear division may not be followed by cell division.
    GO:0051301    cell division    The process resulting in division and partitioning of components of a cell to form more cells; may or may not be accompanied by the physical separation of a cell into distinct, individually membrane-bounded daughter cells.
    GO:1900364    negative regulation of mRNA polyadenylation    Any process that stops, prevents or reduces the frequency, rate or extent of mRNA polyadenylation.
    GO:0045737    positive regulation of cyclin-dependent protein serine/threonine kinase activity    Any process that activates or increases the frequency, rate or extent of CDK activity.
    GO:1901409    positive regulation of phosphorylation of RNA polymerase II C-terminal domain    Any process that activates or increases the frequency, rate or extent of phosphorylation of RNA polymerase II C-terminal domain.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0050434    positive regulation of viral transcription    Any process that activates or increases the frequency, rate or extent of viral transcription.
    GO:0006468    protein phosphorylation    The process of introducing a phosphate group on to a protein.
    GO:0000079    regulation of cyclin-dependent protein serine/threonine kinase activity    Any process that modulates the frequency, rate or extent of cyclin-dependent protein serine/threonine kinase activity.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0042795    snRNA transcription from RNA polymerase II promoter    The synthesis of small nuclear RNA (snRNA) from a DNA template by RNA Polymerase II (Pol II), originating at a Pol II promoter.
    GO:0006368    transcription elongation from RNA polymerase II promoter    The extension of an RNA molecule after transcription initiation and promoter clearance at an RNA polymerase II promoter by the addition of ribonucleotides catalyzed by RNA polymerase II.
    GO:0006366    transcription from RNA polymerase II promoter    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.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
cellular component
    GO:0008024    cyclin/CDK positive transcription elongation factor complex    A transcription elongation factor complex that facilitates the transition from abortive to productive elongation by phosphorylating the CTD domain of the large subunit of DNA-directed RNA polymerase II, holoenzyme. Contains a cyclin and a cyclin-dependent protein kinase catalytic subunit.
    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:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    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.
