molecular function |
| GO:0001671 | | ATPase activator activity | | Binds to and increases the ATP hydrolysis activity of an ATPase. |
| GO:0051117 | | ATPase binding | | Interacting selectively and non-covalently with an ATPase, any enzyme that catalyzes the hydrolysis of ATP. |
| GO:0030544 | | Hsp70 protein binding | | Interacting selectively and non-covalently with Hsp70 proteins, any of a group of heat shock proteins around 70kDa in size. |
| GO:0051087 | | chaperone binding | | Interacting selectively and non-covalently with a chaperone protein, a class of proteins that bind to nascent or unfolded polypeptides and ensure correct folding or transport. |
| GO:0015036 | | disulfide oxidoreductase activity | | Catalysis of the reaction: substrate with reduced sulfide groups = substrate with oxidized disulfide bonds. |
| GO:0051787 | | misfolded protein binding | | Interacting selectively and non-covalently with a misfolded protein. |
| GO:0016491 | | oxidoreductase activity | | Catalysis of an oxidation-reduction (redox) reaction, a reversible chemical reaction in which the oxidation state of an atom or atoms within a molecule is altered. One substrate acts as a hydrogen or electron donor and becomes oxidized, while the other acts as hydrogen or electron acceptor and becomes reduced. |
| GO:0016671 | | oxidoreductase activity, acting on a sulfur group of donors, disulfide as acceptor | | Catalysis of an oxidation-reduction (redox) reaction in which a sulfur-containing group acts as a hydrogen or electron donor and reduces disulfide. |
| 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). |
| GO:0015035 | | protein disulfide oxidoreductase activity | | Catalysis of the reaction: a protein with reduced sulfide groups = a protein with oxidized disulfide bonds. |
biological process |
| GO:0045454 | | cell redox homeostasis | | Any process that maintains the redox environment of a cell or compartment within a cell. |
| GO:0070059 | | intrinsic apoptotic signaling pathway in response to endoplasmic reticulum stress | | A series of molecular signals in which an intracellular signal is conveyed to trigger the apoptotic death of a cell. The pathway is induced in response to a stimulus indicating endoplasmic reticulum (ER) stress, and ends when the execution phase of apoptosis is triggered. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen. |
| GO:0001933 | | negative regulation of protein phosphorylation | | Any process that stops, prevents or reduces the rate of addition of phosphate groups to amino acids within a protein. |
| GO:0055114 | | oxidation-reduction process | | A metabolic process that results in the removal or addition of one or more electrons to or from a substance, with or without the concomitant removal or addition of a proton or protons. |
| GO:0032781 | | positive regulation of ATPase activity | | Any process that activates or increases the rate of ATP hydrolysis by an ATPase. |
| GO:0034975 | | protein folding in endoplasmic reticulum | | A protein folding process that takes place in the endoplasmic reticulum (ER). Secreted, plasma membrane and organelle proteins are folded in the ER, assisted by chaperones and foldases (protein disulphide isomerases), and additional factors required for optimal folding (ATP, Ca2+ and an oxidizing environment to allow disulfide bond formation). |
| 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:0030433 | | ubiquitin-dependent ERAD pathway | | The series of steps necessary to target endoplasmic reticulum (ER)-resident proteins for degradation by the cytoplasmic proteasome. Begins with recognition of the ER-resident protein, includes retrotranslocation (dislocation) of the protein from the ER to the cytosol, protein ubiquitination necessary for correct substrate transfer, transport of the protein to the proteasome, and ends with degradation of the protein by the cytoplasmic proteasome. |
cellular component |
| 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:0034663 | | endoplasmic reticulum chaperone complex | | A protein complex that is located in the endoplasmic reticulum and is composed of chaperone proteins, including BiP, GRP94; CaBP1, protein disulfide isomerase (PDI), ERdj3, cyclophilin B, ERp72, GRP170, UDP-glucosyltransferase, and SDF2-L1. |
| GO:0005788 | | endoplasmic reticulum lumen | | The volume enclosed by the membranes of the endoplasmic reticulum. |
| GO:0016020 | | membrane | | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
