3 GO annotations of cellular component
Name | Definition |
---|---|
cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
extracellular region | The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite. |
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. |
3 GO annotations of molecular function
Name | Definition |
---|---|
RNA polymerase II-specific DNA-binding transcription factor binding | Binding to a sequence-specific DNA binding RNA polymerase II transcription factor, any of the factors that interact selectively and non-covalently with a specific DNA sequence in order to modulate transcription. |
ubiquitin protein ligase activity | Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond: an isopeptide bond between the C-terminal glycine of ubiquitin and the epsilon-amino group of lysine residues in the substrate or, in the linear extension of ubiquitin chains, a peptide bond the between the C-terminal glycine and N-terminal methionine of ubiquitin residues. |
ubiquitin-protein transferase activity | Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages. |
17 GO annotations of biological process
Name | Definition |
---|---|
extracellular transport | The transport of substances that occurs outside cells. |
negative regulation of DNA-binding transcription factor activity | Any process that stops, prevents, or reduces the frequency, rate or extent of the activity of a transcription factor, any factor involved in the initiation or regulation of transcription. |
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 protein transport | Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of a protein into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
negative regulation of transcription by RNA polymerase II | Any process that stops, prevents, or reduces the frequency, rate or extent of transcription mediated by RNA polymerase II. |
negative regulation of transcription, DNA-templated | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
negative regulation of transporter activity | Any process that stops or reduces the activity of a transporter. |
positive regulation of protein catabolic process | Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds. |
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. |
proteasome-mediated ubiquitin-dependent protein catabolic process | The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome. |
protein autoubiquitination | The ubiquitination by a protein of one or more of its own amino acid residues, or residues on an identical protein. Ubiquitination occurs on the lysine residue by formation of an isopeptide crosslink. |
protein K63-linked ubiquitination | A protein ubiquitination process in which a polymer of ubiquitin, formed by linkages between lysine residues at position 63 of the ubiquitin monomers, is added to a protein. K63-linked ubiquitination does not target the substrate protein for degradation, but is involved in several pathways, notably as a signal to promote error-free DNA postreplication repair. |
protein polyubiquitination | Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain. |
protein ubiquitination | The process in which one or more ubiquitin groups are added to a protein. |
regulation of ion transmembrane transport | Any process that modulates the frequency, rate or extent of the directed movement of ions from one side of a membrane to the other. |
regulation of membrane potential | Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane. |
regulation of potassium ion transmembrane transporter activity | Any process that modulates the frequency, rate or extent of potassium ion transmembrane transporter activity. |
