CAMKI/CAMK1 Zusammenfassung und Proteininformation

CAMKI/CAMK1 Hintergrund

Zusammenfassung der Gene: Calcium/calmodulin-dependent protein kinase I is expressed in many tissues and is a component of a calmodulin-dependent protein kinase cascade. Calcium/calmodulin directly activates calcium/calmodulin-dependent protein kinase I by binding to the enzyme and indirectly promotes the phosphorylation and synergistic activation of the enzyme by calcium/calmodulin-dependent protein kinase I kinase.
General information above from NCBI
Katalytische Aktivität: ATP + a protein = ADP + a phosphoprotein.
Enzymregulation: Activated by Ca(2+)/calmodulin. Binding of calmodulin results in conformational change that relieves intrasteric autoinhibition and allows phosphorylation of Thr-177 within the activation loop by CaMKK1 or CaMKK2. Phosphorylation of Thr-177 results in several fold increase in total activity. Unlike CaMK4, is unable to exhibit autonomous activity after Ca(2+)/calmodulin activation.
Untereinheitenstruktur: Monomer. Interacts with XPO1 (By similarity). Interacts with MARK2, ARHGEF7/BETAPIX and GIT1.
Domäne: The autoinhibitory domain overlaps with the calmodulin binding region and interacts in the inactive folded state with the catalytic domain as a pseudosubstrate.
Subzelluläre Position: Cytoplasm (By similarity). Nucleus (By similarity). Note=Predominantly cytoplasmic (By similarity).
Gewebespezifität: Widely expressed. Expressed in cells of the zona glomerulosa of the adrenal cortex.
Posttranslational: Phosphorylated by CaMKK1 and CaMKK2 on Thr-177.
Sequenzähnlichkeit: Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily.
Contains 1 protein kinase domain.C
General information above from UniProt

Calcium/calmodulin-dependent protein kinase or CaM kinases are serine/threonine-specific protein kinases that are primarily regulated by the Calcium/calmodulin complex. These kinases show a memory effect on activation. CaM kinases activity can outlast the intracellular calcium transient that is needed to activate it. In neurons, this property is important for the induction of synaptic plasticity. Pharmacological inhibition of CaM kinases II blocks the induction of long-term potentiation. Upon activation, CaM kinases II phosphorylates postsynaptic glutamate receptors and changes the electrical properties of the synapse.

Calcium/calmodulin-dependent protein kinase type 1D, also known as CaM kinase I delta, CaM kinase ID, CaMKI-like protein kinase, CKLiK and CAMK1D, is a member of the protein kinase superfamily and CaMK subfamily. It contains one protein kinase domain. CAMK1D is broadly expressed. It is highly and mostly expressed in polymorphonuclear leukocytes (neutrophilic and eosinophilic granulocytes) while little or no expression is observed in monocytes and lymphocytes. Engineered overexpression of CAMK1D in non-tumorigenic breast epithelial cells led to increased cell proliferation, and molecular and phenotypic alterations indicative of epithelial-mesenchymal transition (EMT), including loss of cell-cell adhesions and increased cell migration and invasion. CAMK1D is a potential therapeutic target with particular relevance to clinically unfavorable basal-like tumors.
