molecular function |
| GO:0044325 | | ion channel binding | | Interacting selectively and non-covalently with one or more specific sites on an ion channel, a protein complex that spans a membrane and forms a water-filled channel across the phospholipid bilayer allowing selective ion transport down its electrochemical gradient. |
| GO:0003674 | | molecular_function | | Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. |
| 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). |
biological process |
| GO:0036499 | | PERK-mediated unfolded protein response | | A series of molecular signals mediated by the endoplasmic reticulum membrane stress sensor PERK (PKR-like ER kinase). Begins with activation of PERK in response to endoplasmic reticulum (ER) stress and ends with regulation of a downstream cellular process, e.g. transcription. The main substrate of PERK is the translation initiation factor eIF2alpha. Serine-phosphorylation of eIF2alpha by PERK inactivates eIF2alpha and inhibits general protein translation. In addition, eIF2alpha phosphorylation preferentially increases the translation of selective mRNAs such as ATF4 (activating transcription factor 4), which up regulates a subset of UPR genes required to restore folding capacity. |
| GO:0006874 | | cellular calcium ion homeostasis | | Any process involved in the maintenance of an internal steady state of calcium ions at the level of a cell. |
| GO:0032469 | | endoplasmic reticulum calcium ion homeostasis | | Any process involved in the maintenance of an internal steady state of calcium ions within the endoplasmic reticulum of a cell or between the endoplasmic reticulum and its surroundings. |
| GO:0030968 | | endoplasmic reticulum unfolded protein response | | The series of molecular signals generated as a consequence of the presence of unfolded proteins in the endoplasmic reticulum (ER) or other ER-related stress; results in changes in the regulation of transcription and translation. |
| GO:0043154 | | negative regulation of cysteine-type endopeptidase activity involved in apoptotic process | | Any process that stops, prevents, or reduces the frequency, rate or extent of a cysteine-type endopeptidase activity involved in the apoptotic process. |
| GO:1902236 | | negative regulation of endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway | | Any process that stops, prevents or reduces the frequency, rate or extent of an endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway. |
| GO:2001243 | | negative regulation of intrinsic apoptotic signaling pathway | | Any process that stops, prevents or reduces the frequency, rate or extent of intrinsic apoptotic signaling pathway. |
| GO:1903071 | | positive regulation of ER-associated ubiquitin-dependent protein catabolic process | | Any process that activates or increases the frequency, rate or extent of ER-associated ubiquitin-dependent protein catabolic process. |
| GO:0032092 | | positive regulation of protein binding | | Any process that activates or increases the frequency, rate or extent of protein binding. |
| GO:1903069 | | regulation of ER-associated ubiquitin-dependent protein catabolic process | | Any process that modulates the frequency, rate or extent of ER-associated ubiquitin-dependent protein catabolic process. |
| GO:1902235 | | regulation of endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway | | Any process that modulates the frequency, rate or extent of an endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway. |
| GO:0031396 | | regulation of protein ubiquitination | | Any process that modulates the frequency, rate or extent of the addition of ubiquitin groups to a protein. |
| GO:0034976 | | response to endoplasmic reticulum stress | | 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 stress acting at the endoplasmic reticulum. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen. |
| GO:0006986 | | response to unfolded protein | | 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 unfolded protein stimulus. |
| GO:0030970 | | retrograde protein transport, ER to cytosol | | The directed movement of unfolded or misfolded proteins from the endoplasmic reticulum to the cytosol through the translocon. |
| GO:0006511 | | 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 a ubiquitin group, or multiple ubiquitin groups, to the protein. |
cellular component |
| GO:1990037 | | Lewy body core | | The center portion of a Lewy body. In Parkinson's disease, it contains a matted meshwork of filaments. |
| GO:0034704 | | calcium channel complex | | An ion channel complex through which calcium ions pass. |
| GO:0005783 | | endoplasmic reticulum | | The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached). |
| GO:0005789 | | endoplasmic reticulum membrane | | The lipid bilayer surrounding the endoplasmic reticulum. |
| GO:0016021 | | integral component of membrane | | The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
