kinase regulator activity
Definition
Target type: molecularfunction
Modulates the activity of a kinase, an enzyme which catalyzes of the transfer of a phosphate group, usually from ATP, to a substrate molecule. [GOC:ai]
Kinase regulator activity encompasses a diverse range of molecular functions that modulate the activity of kinases, enzymes that catalyze the transfer of a phosphate group from a donor molecule, typically ATP, to a substrate. Kinases play crucial roles in numerous cellular processes, including signal transduction, cell cycle regulation, metabolism, and gene expression. Kinase regulators can either activate or inhibit kinase activity through various mechanisms, including:
* **Binding to and altering the conformation of kinases:** Some regulators bind to kinases and induce conformational changes that either activate or inhibit their catalytic activity. This can involve altering the accessibility of the active site, promoting or disrupting the binding of substrates or cofactors.
* **Providing or removing activating or inhibitory modifications:** Kinase regulators can directly modify kinases through phosphorylation, acetylation, methylation, or other post-translational modifications, which can either enhance or suppress their activity.
* **Scaffolding and assembly of kinase complexes:** Kinase regulators can act as scaffolding proteins, bringing together kinases and their substrates or other signaling components to facilitate specific interactions and signaling events.
* **Controlling kinase localization and trafficking:** Some regulators influence the subcellular localization of kinases by directing them to specific compartments or preventing their translocation. This can regulate their accessibility to substrates and signaling pathways.
* **Modulating the expression levels of kinases:** Kinase regulators can influence the transcription or translation of kinase genes, ultimately affecting the amount of kinase protein available in the cell.
Kinase regulators are essential for maintaining proper cellular function and signaling. Dysregulation of kinase regulator activity can lead to a variety of diseases, including cancer, metabolic disorders, and neurodegenerative diseases. Understanding the diverse molecular functions of kinase regulators is crucial for developing effective therapies targeting these diseases.'

Compounds (10)
| Compound | Definition | Classes | Roles |
|---|---|---|---|
| ethacrynic acid | etacrynic acid : An aromatic ether that is phenoxyacetic acid in which the phenyl ring is substituted by chlorines at positions 2 and 3, and by a 2-methylidenebutanoyl group at position 4. It is a loop diuretic used to treat high blood pressure resulting from diseases such as congestive heart failure, liver failure, and kidney failure. It is also a glutathione S-transferase (EC 2.5.1.18) inhibitor. Ethacrynic Acid: A compound that inhibits symport of sodium, potassium, and chloride primarily in the ascending limb of Henle, but also in the proximal and distal tubules. This pharmacological action results in excretion of these ions, increased urinary output, and reduction in extracellular fluid. This compound has been classified as a loop or high ceiling diuretic. | aromatic ether; aromatic ketone; dichlorobenzene; monocarboxylic acid | EC 2.5.1.18 (glutathione transferase) inhibitor; ion transport inhibitor; loop diuretic |
| d-alpha tocopherol | (R,R,R)-alpha-tocopherol : An alpha-tocopherol that has R,R,R configuration. The naturally occurring stereoisomer of alpha-tocopherol, it is found particularly in sunflower and olive oils. tocopherol : A collective name for a group of closely related lipids that contain a chroman-6-ol nucleus substituted at position 2 by a methyl group and by a saturated hydrocarbon chain consisting of three isoprenoid units. They are designated as alpha-, beta-, gamma-, and delta-tocopherol depending on the number and position of additional methyl substituents on the aromatic ring. Tocopherols occur in vegetable oils and vegetable oil products, almost exclusively with R,R,R configuration. Tocotrienols differ from tocopherols only in having three double bonds in the hydrocarbon chain. vitamin E : Any member of a group of fat-soluble chromanols that exhibit biological activity against vitamin E deficiency. The vitamers in this class consists of a chroman-6-ol core which is substituted at position 2 by a methyl group and (also at position 2) either a saturated or a triply-unsaturated hydrocarbon chain consisting of three isoprenoid units. The major function of vitamin E is to act as a natural antioxidant by scavenging free radicals and molecular oxygen. Vitamin E: A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS. | alpha-tocopherol | algal metabolite; antiatherogenic agent; anticoagulant; antioxidant; antiviral agent; EC 2.7.11.13 (protein kinase C) inhibitor; immunomodulator; micronutrient; nutraceutical; plant metabolite |
