12 GO annotations of cellular component
| Name | Definition |
|---|---|
| catalytic step 2 spliceosome | A spliceosomal complex that contains three snRNPs, including U5, bound to a splicing intermediate in which the first catalytic cleavage of the 5' splice site has occurred. The precise subunit composition differs significantly from that of the catalytic step 1, or activated, spliceosome, and includes many proteins in addition to those found in the associated snRNPs. |
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| dendrite | A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| exon-exon junction complex | A multi-subunit complex deposited by the spliceosome upstream of messenger RNA exon-exon junctions. The exon-exon junction complex provides a binding platform for factors involved in mRNA export and nonsense-mediated mRNA decay. |
| glutamatergic synapse | A synapse that uses glutamate as a neurotransmitter. |
| neuronal cell body | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| nuclear speck | A discrete extra-nucleolar subnuclear domain, 20-50 in number, in which splicing factors are seen to be localized by immunofluorescence microscopy. |
| 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. |
| 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. |
| postsynaptic cytosol | The region of the cytosol consisting of all cytosol that is part of the postsynapse. |
| ribonucleoprotein complex | A macromolecular complex that contains both RNA and protein molecules. |
| U2-type catalytic step 1 spliceosome | A spliceosomal complex that is formed by the displacement of the U1 and U4 snRNPs from the precatalytic spliceosome; the U2, U5 and U6 snRNPs remain associated with the mRNA. This complex, sometimes called the activated spliceosome, is the catalytically active form of the spliceosome, and includes many proteins in addition to those found in the U2, and U5 and U6 snRNPs. |
10 GO annotations of molecular function
| Name | Definition |
|---|---|
| ATP binding | Binding to ATP, adenosine 5'-triphosphate, a universally important coenzyme and enzyme regulator. |
| ATP hydrolysis activity | Catalysis of the reaction: ATP + H2O = ADP + H+ phosphate. ATP hydrolysis is used in some reactions as an energy source, for example to catalyze a reaction or drive transport against a concentration gradient. |
| mRNA binding | Binding to messenger RNA (mRNA), an intermediate molecule between DNA and protein. mRNA includes UTR and coding sequences, but does not contain introns. |
| poly(A) binding | Binding to a sequence of adenylyl residues in an RNA molecule, such as the poly(A) tail, a sequence of adenylyl residues at the 3' end of eukaryotic mRNA. |
| ribonucleoprotein complex binding | Binding to a complex of RNA and protein. |
| RNA binding | Binding to an RNA molecule or a portion thereof. |
| RNA helicase activity | Unwinding of an RNA helix, driven by ATP hydrolysis. |
| RNA stem-loop binding | Binding to a stem-loop in an RNA molecule. An RNA stem-loop is a secondary RNA structure consisting of a double-stranded RNA (dsRNA) stem and a terminal loop. |
| selenocysteine insertion sequence binding | Binding to a selenocysteine insertion sequence (SECIS), a regulatory sequence within mRNA which directs incorporation of a selenocysteine at a stop codon (UGA) during translation. |
| translation regulator activity | Any molecular function involved in the initiation, activation, perpetuation, repression or termination of polypeptide synthesis at the ribosome. |
22 GO annotations of biological process
| Name | Definition |
|---|---|
| associative learning | Learning by associating a stimulus (the cause) with a particular outcome (the effect). |
| cellular response to brain-derived neurotrophic factor stimulus | A process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a brain-derived neurotrophic factor stimulus. |
| cellular response to selenite ion | Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a selenite ion stimulus. |
| embryonic cranial skeleton morphogenesis | The process in which the anatomical structures of the cranial skeleton are generated and organized during the embryonic phase. |
| exploration behavior | The specific behavior of an organism in response to a novel environment or stimulus. |
| mRNA splicing, via spliceosome | The joining together of exons from one or more primary transcripts of messenger RNA (mRNA) and the excision of intron sequences, via a spliceosomal mechanism, so that mRNA consisting only of the joined exons is produced. |
| mRNA transport | The directed movement of mRNA, messenger ribonucleic acid, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
| negative regulation of excitatory postsynaptic potential | Any process that prevents the establishment or decreases the extent of the excitatory postsynaptic potential (EPSP) which is a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell. The flow of ions that causes an EPSP is an excitatory postsynaptic current (EPSC) and makes it easier for the neuron to fire an action potential. |
| negative regulation of gene expression | Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA). |
| negative regulation of selenocysteine incorporation | Any process that stops, prevents or reduces the frequency, rate or extent of selenocysteine incorporation. |
| negative regulation of selenocysteine insertion sequence binding | Any process that stops, prevents or reduces the frequency, rate or extent of selenocysteine insertion sequence binding. |
| negative regulation of translation | Any process that stops, prevents, or reduces the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA. |
| nuclear-transcribed mRNA catabolic process, nonsense-mediated decay | The nonsense-mediated decay pathway for nuclear-transcribed mRNAs degrades mRNAs in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins. |
| positive regulation of mRNA splicing, via spliceosome | Any process that activates or increases the rate or extent of mRNA splicing via a spliceosomal mechanism. |
| positive regulation of transcription by RNA polymerase II | Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter. |
| positive regulation of translation | Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA. |
| regulation of alternative mRNA splicing, via spliceosome | Any process that modulates the frequency, rate or extent of alternative splicing of nuclear mRNAs. |
| regulation of mRNA binding | Any process that modulates the frequency, rate or extent of mRNA binding. |

| regulation of translation at postsynapse, modulating synaptic transmission | Any process that modulates synaptic transmission by regulating translation occurring at the postsynapse. |
| response to organic cyclic compound | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an organic cyclic compound stimulus. |
| rRNA processing | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. |
