VACUOLAR PROTEIN SORTING-ASSOCIATED PROTEIN VTA1 HOMOLOG (PTHR46009) |
Descriptions
Vta is a cofactor of AAA-ATPase Vps4 via Vps4 stimulatory element (VSE), which is required to functionalize the endosomal sorting complexes required for transport (ESCRTs). The VSE domain is autoinhibited by the Vta1 linker region (183-266), inhibiting the Vps4 stimulation. ESCRT-III binding to the Vta1 microtubule interacting and trafficking domains relieves linker region autoinhibition of the VSE to produce maximal activation of Vps4 during ESCRT function. Deletion of amino-terminal portions of the linker region results in a hyperactive form of Vta1, which stimulates Vps4 function by facilitating oligomerization of Vps4.

9 GO annotations of cellular component
| Name | Definition |
|---|---|
| cytoplasm | The contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| cytosol | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| 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. |
| fungal-type cell wall | A rigid yet dynamic structure surrounding the plasma membrane that affords protection from stresses and contributes to cell morphogenesis, consisting of extensively cross-linked glycoproteins and carbohydrates. The glycoproteins may be modified with N- or O-linked carbohydrates, or glycosylphosphatidylinositol (GPI) anchors; the polysaccharides are primarily branched glucans, including beta-linked and alpha-linked glucans, and may also include chitin and other carbohydrate polymers, but not cellulose or pectin. Enzymes involved in cell wall biosynthesis are also found in the cell wall. Note that some forms of fungi develop a capsule outside of the cell wall under certain circumstances; this is considered a separate structure. |
| fungal-type vacuole membrane | The lipid bilayer surrounding a vacuole, the shape of which correlates with cell cycle phase. The membrane separates its contents from the cytoplasm of the cell. An example of this structure is found in Saccharomyces cerevisiae. |
| 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. |
| 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. |
| plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
| transcription repressor complex | A protein complex that possesses activity that prevents or downregulates transcription. |
7 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-dependent protein folding chaperone | Binding to a protein or a protein-containing complex to assist the protein folding process, driven by ATP hydrolysis. |
| heat shock protein binding | Binding to a heat shock protein, a protein synthesized or activated in response to heat shock. |
| protein folding chaperone | Binding to a protein or a protein-containing complex to assist the protein folding process. |
| tRNA binding | Binding to a transfer RNA. |
| unfolded protein binding | Binding to an unfolded protein. |
8 GO annotations of biological process
| Name | Definition |
|---|---|
| chaperone cofactor-dependent protein refolding | The process of assisting in the correct posttranslational noncovalent assembly of proteins, which is dependent on additional protein cofactors. This process occurs over one or several cycles of nucleotide hydrolysis-dependent binding and release. |
| negative regulation of DNA-templated transcription | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
| 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 folding | The process of assisting in the covalent and noncovalent assembly of single chain polypeptides or multisubunit complexes into the correct tertiary structure. |
| protein refolding | The process carried out by a cell that restores the biological activity of an unfolded or misfolded protein, using helper proteins such as chaperones. |
| response to oxygen levels | 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 a stimulus reflecting the presence, absence, or concentration of oxygen. |
| SRP-dependent cotranslational protein targeting to membrane, translocation | The process during cotranslational membrane targeting wherein proteins move across a membrane. SRP and its receptor initiate the transfer of the nascent chain across the endoplasmic reticulum (ER) membrane; they then dissociate from the chain, which is transferred to a set of transmembrane proteins, collectively called the translocon. Once the nascent chain translocon complex is assembled, the elongating chain passes directly from the large ribosomal subunit into the centers of the translocon, a protein-lined channel within the membrane. The growing chain is never exposed to the cytosol and does not fold until it reaches the ER lumen. |
| tRNA import into nucleus | The directed movement of tRNA from the cytoplasm to the nucleus. |
