    GO:0098789    pre-mRNA cleavage required for polyadenylation    The targeted, endonucleolytic cleavage of a pre-mRNA, required for polyadenylation of the 3' end. This cleavage is directed by binding sites near the 3' end of the mRNA and leaves a 3' hydoxyl end which then becomes a target for adenylation.
    GO:1900363    regulation of mRNA polyadenylation    Any process that modulates the frequency, rate or extent of mRNA polyadenylation.
    GO:0006417    regulation of translation    Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
    GO:0006446    regulation of translational initiation    Any process that modulates the frequency, rate or extent of translational initiation.
    GO:0006408    snRNA export from nucleus    The directed movement of snRNA from the nucleus to the cytoplasm.
    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:0006369    termination of RNA polymerase II transcription    The process in which the synthesis of an RNA molecule by RNA polymerase II using a DNA template is completed.
    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:0006810    transport    The directed movement of substances (such as macromolecules, small molecules, ions) or cellular components (such as complexes and organelles) into, out of or within a cell, or between cells, or within a multicellular organism by means of some agent such as a transporter, pore or motor protein.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0005829    cytosol    The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
    GO:0005845    mRNA cap binding complex    Any protein complex that binds to an mRNA cap at any time in the lifetime of the mRNA.
    GO:0005846    nuclear cap binding complex    A conserved heterodimeric protein complex that binds to the 5' terminal cap structure m7G(5')ppp(5')N of nascent eukaryotic RNA polymerase II transcripts such as pre-mRNA and U snRNA. The consists of proteins known as CBP20 and CBP80, binds to cap structures in the nucleus, and is involved in pre-mRNA splicing, 3'-end formation, and RNA nuclear export.
    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.
