Descriptions
(Annotation based on sequence homology with O62305)
CaMKII is one of the most important transducers of Ca2+signals in a variety of cell types and is highly conserved across animal species. The calmodulin-responsive regulatory segment forms a coiled coil structure that blocks peptide and ATP binding to the otherwise intrinsically active kinase domain.Ca2+/CaM removes the autoinhibitory regulatory segment located C-terminal to the kinase domain which releases the catalytic activity of the enzyme.

| Name | Definition |
|---|---|
| anchoring junction | A cell junction that mechanically attaches a cell (and its cytoskeleton) to neighboring cells or to the extracellular matrix. |
| axon | The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter. |
| calcium- and calmodulin-dependent protein kinase complex | An enzyme complex which in eukaryotes is composed of four different chains: alpha, beta, gamma, and delta. The different isoforms assemble into homo- or heteromultimeric holoenzymes composed of 8 to 12 subunits. Catalyzes the phosphorylation of proteins to O-phosphoproteins. |
| 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. |
| dendrite | A neuron projection that has a short, tapering, morphology. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body. |
| dendrite cytoplasm | All of the contents of a dendrite, excluding the surrounding plasma membrane. |
| dendritic spine | A small, membranous protrusion from a dendrite that forms a postsynaptic compartment, typically receiving input from a single presynapse. They function as partially isolated biochemical and an electrical compartments. Spine morphology is variable:they can be thin, stubby, mushroom, or branched, with a continuum of intermediate morphologies. They typically terminate in a bulb shape, linked to the dendritic shaft by a restriction. Spine remodeling is though to be involved in synaptic plasticity. |
| glutamatergic postsynaptic density | The post-synaptic specialization of a glutamatergic excitatory synapse. |
| glutamatergic synapse | A synapse that uses glutamate as a neurotransmitter. |
| membrane | A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it. |
| 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. |
| neuron projection | A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. |
| neuronal cell body | The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. |
| 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. |
| postsynaptic cytosol | The region of the cytosol consisting of all cytosol that is part of the postsynapse. |
| postsynaptic density | An electron dense network of proteins within and adjacent to the postsynaptic membrane of an asymmetric, neuron-neuron synapse. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components. |
| postsynaptic specialization membrane | The membrane component of the postsynaptic specialization. This is the region of the postsynaptic membrane in which the population of neurotransmitter receptors involved in synaptic transmission are concentrated. |
| presynaptic cytosol | The region of the cytosol consisting of all cytosol that is part of the presynapse. |
| Schaffer collateral - CA1 synapse | A synapse between the Schaffer collateral axon of a CA3 pyramidal cell and a CA1 pyramidal cell. |
| synapse | The junction between an axon of one neuron and a dendrite of another neuron, a muscle fiber or a glial cell. As the axon approaches the synapse it enlarges into a specialized structure, the presynaptic terminal bouton, which contains mitochondria and synaptic vesicles. At the tip of the terminal bouton is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic terminal bouton secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane. |
