Enables
This protein enables 4 target(s):
| Target | Category | Definition |
|---|---|---|
| protein binding | molecular function | Binding to a protein. [GOC:go_curators] |
| ionotropic glutamate receptor binding | molecular function | Binding to an ionotropic glutamate receptor. Ionotropic glutamate receptors bind glutamate and exert an effect through the regulation of ion channels. [GOC:bf, ISBN:0198506732] |
| channel regulator activity | molecular function | Binds to and modulates the activity of a channel. A channel catalyzes energy-independent facilitated diffusion, mediated by passage of a solute through a transmembrane aqueous pore or channel. [GOC:mah] |
| voltage-gated calcium channel activity | molecular function | Enables the transmembrane transfer of a calcium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded. [GOC:mtg_transport, GOC:tb, ISBN:0815340729] |
Located In
This protein is located in 8 target(s):
| Target | Category | Definition |
|---|---|---|
| plasma membrane | cellular component | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363] |
| cell surface | cellular component | The external part of the cell wall and/or plasma membrane. [GOC:jl, GOC:mtg_sensu, GOC:sm] |
| endocytic vesicle membrane | cellular component | The lipid bilayer surrounding an endocytic vesicle. [GOC:mah] |
| somatodendritic compartment | cellular component | The region of a neuron that includes the cell body (cell soma) and dendrite(s), but excludes the axon. [GOC:pad, GOC:PARL] |
| cerebellar mossy fiber | cellular component | An axon arising from cerebellar projecting cells in the cochlea, vestibular nuclei, spinal cord, reticular formation, cerebellar nuclei and basilar pontine nuclei. Mossy fibers enter through all three cerebellar peduncles and send collaterals to the deep cerebellar nuclei, then branch in the white matter and terminate in the granule cell layer. Through this branching, a given mossy fiber can innervate several folia. Mossy fibers synapse on granule cells. The synaptic contacts are made at enlargements along the length of the mossy fiber called mossy fiber rosettes. The enlargements of the rosettes give the axons a mossy-looking appearance in Golgi stained preparations. [NIF_Subcellular:nlx_subcell_20090209] |
| Schaffer collateral - CA1 synapse | cellular component | A synapse between the Schaffer collateral axon of a CA3 pyramidal cell and a CA1 pyramidal cell. [PMID:16399689] |
| hippocampal mossy fiber to CA3 synapse | cellular component | One of the giant synapses that form between the mossy fiber axons of dentate gyrus granule cells and the large complex spines of CA3 pyramidal cells. It consists of a giant bouton known as the mossy fiber expansion, synapsed to the complex, multiheaded spine (thorny excresence) of a CA3 pyramidal cell. [DOI:10.1002/1096-9861, PMID:13869693, PMID:23264762] |
| glutamatergic synapse | cellular component | A synapse that uses glutamate as a neurotransmitter. [GOC:dos] |
Active In
This protein is active in 1 target(s):
| Target | Category | Definition |
|---|---|---|
| postsynaptic density membrane | cellular component | The membrane component of the postsynaptic density. This is the region of the postsynaptic membrane in which the population of neurotransmitter receptors involved in synaptic transmission are concentrated. [GOC:dos] |
Part Of
This protein is part of 2 target(s):
| Target | Category | Definition |
|---|---|---|
| voltage-gated calcium channel complex | cellular component | A protein complex that forms a transmembrane channel through which calcium ions may pass in response to changes in membrane potential. [GOC:mah] |
| AMPA glutamate receptor complex | cellular component | An assembly of four or five subunits which form a structure with an extracellular N-terminus and a large loop that together form the ligand binding domain. The C-terminus is intracellular. The ionotropic glutamate receptor complex itself acts as a ligand gated ion channel; on binding glutamate, charged ions pass through a channel in the center of the receptor complex. The AMPA receptors mediate fast synaptic transmission in the CNS and are composed of subunits GluR1-4, products from separate genes. These subunits have an extracellular N-terminus and an intracellular C-terminus. [GOC:ef] |

| neuromuscular junction development | biological process | A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a neuromuscular junction. [GOC:mtg_OBO2OWL_2013] |
| response to calcium ion | biological process | 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 a calcium ion stimulus. [GOC:ai] |
| membrane depolarization | biological process | The process in which membrane potential decreases with respect to its steady-state potential, usually from negative potential to a more positive potential. For example, the initial depolarization during the rising phase of an action potential is in the direction from the negative steady-state resting potential towards the positive membrane potential that will be the peak of the action potential. [GOC:dh, Wikipedia:Depolarization] |
| membrane hyperpolarization | biological process | The process in which membrane potential increases with respect to its steady-state potential, usually from negative potential to a more negative potential. For example, during the repolarization phase of an action potential the membrane potential often becomes more negative or hyperpolarized before returning to the steady-state resting potential.
