amyloid-beta bindingmolecular functionBinding to an amyloid-beta peptide/protein. [GOC:hjd]
voltage-gated calcium channel activitymolecular functionEnables 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]
protein bindingmolecular functionBinding to a protein. [GOC:go_curators]
high voltage-gated calcium channel activitymolecular functionEnables the transmembrane transfer of a calcium ion by a high voltage-gated channel. A high voltage-gated channel is a channel whose open state is dependent on high voltage across the membrane in which it is embedded. [GOC:mtg_transport, ISBN:0815340729, PMID:16382099]
syntaxin bindingmolecular functionBinding to a syntaxin, a SNAP receptor involved in the docking of synaptic vesicles at the presynaptic zone of a synapse. [ISBN:0198506732]
metal ion bindingmolecular functionBinding to a metal ion. [GOC:ai]

Located In

This protein is located in 7 target(s):

TargetCategoryDefinition
nucleuscellular componentA 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. [GOC:go_curators]
cytoplasmcellular componentThe contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. [ISBN:0198547684]
plasma membranecellular componentThe membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. [ISBN:0716731363]
membranecellular componentA lipid bilayer along with all the proteins and protein complexes embedded in it and attached to it. [GOC:dos, GOC:mah, ISBN:0815316194]
cell projectioncellular componentA prolongation or process extending from a cell, e.g. a flagellum or axon. [GOC:jl, http://www.cogsci.princeton.edu/~wn/]
neuronal cell bodycellular componentThe portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites. [GOC:go_curators]
synapsecellular componentThe 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. [GOC:aruk, ISBN:0198506732, PMID:24619342, PMID:29383328, PMID:31998110]

Involved In

This protein is involved in 7 target(s):

TargetCategoryDefinition
positive regulation of cytosolic calcium ion concentrationbiological processAny process that increases the concentration of calcium ions in the cytosol. [GOC:ai]
modulation of chemical synaptic transmissionbiological processAny process that modulates the frequency or amplitude of synaptic transmission, the process of communication from a neuron to a target (neuron, muscle, or secretory cell) across a synapse. Amplitude, in this case, refers to the change in postsynaptic membrane potential due to a single instance of synaptic transmission. [GOC:ai]
calcium ion transmembrane transportbiological processA process in which a calcium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore. [GOC:mah]
response to amyloid-betabiological processAny 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 amyloid-beta stimulus. [GO_REF:0000071, GOC:TermGenie, PMID:23555824]
cellular response to amyloid-betabiological processAny 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 amyloid-beta stimulus. [GO_REF:0000071, GOC:TermGenie, PMID:23555824]
chemical synaptic transmissionbiological processThe vesicular release of classical neurotransmitter molecules from a presynapse, across a chemical synapse, the subsequent activation of neurotransmitter receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse. [GOC:jl, MeSH:D009435]
calcium ion import across plasma membranebiological processThe directed movement of calcium ions from outside of a cell, across the plasma membrane and into the cytosol. [GOC:dos]
