Name | Definition |
---|---|
apical part of cell | The region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue. |
apical plasma membrane | The region of the plasma membrane located at the apical end of the cell. |
basolateral plasma membrane | The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis. |
cytoplasmic side of plasma membrane | The leaflet the plasma membrane that faces the cytoplasm and any proteins embedded or anchored in it or attached to its surface. |
dendrite membrane | The portion of the plasma membrane surrounding a dendrite. |
dendritic spine membrane | The portion of the plasma membrane surrounding a dendritic spine. |
GABA-ergic synapse | A synapse that uses GABA as a neurotransmitter. These synapses are typically inhibitory. |
glutamatergic synapse | A synapse that uses glutamate as a neurotransmitter. |
immunological synapse | An area of close contact between a lymphocyte (T-, B-, or natural killer cell) and a target cell formed through the clustering of particular signaling and adhesion molecules and their associated membrane rafts on both the lymphocyte and the target cell and facilitating activation of the lymphocyte, transfer of membrane from the target cell to the lymphocyte, and in some situations killing of the target cell through release of secretory granules and/or death-pathway ligand-receptor interaction. |
intracellular membrane-bounded organelle | Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane. |
neuronal cell body membrane | The plasma membrane of a neuron cell body - excludes the plasma membrane of cell projections such as axons and dendrites. |
photoreceptor ribbon synapse | A ribbon synapse between a retinal photoreceptor cell (rod or cone) and a retinal bipolar cell. These contain a plate-like synaptic ribbon. |
plasma membrane | The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins. |
presynaptic active zone membrane | The membrane portion of the presynaptic active zone; it is the site where docking and fusion of synaptic vesicles occurs for the release of neurotransmitters. |
presynaptic membrane | A specialized area of membrane of the axon terminal that faces the plasma membrane of the neuron or muscle fiber with which the axon terminal establishes a synaptic junction; many synaptic junctions exhibit structural presynaptic characteristics, such as conical, electron-dense internal protrusions, that distinguish it from the remainder of the axon plasma membrane. |
synaptic vesicle membrane | The lipid bilayer surrounding a synaptic vesicle. |

calcium ion transmembrane transporter activity | Enables the transfer of calcium (Ca) ions from one side of a membrane to the other. |
calmodulin binding | Binding to calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states. |

cellular response to corticosterone stimulus | Any 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 corticosterone stimulus. Corticosterone is a 21 carbon steroid hormone of the corticosteroid type, produced in the cortex of the adrenal glands. In many species, corticosterone is the principal glucocorticoid, involved in regulation of fuel metabolism, immune reactions, and stress responses. |
cellular response to vitamin D | Any 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 vitamin D stimulus. |

negative regulation of cytosolic calcium ion concentration | Any process that decreases the concentration of calcium ions in the cytosol. |
neural retina development | The progression of the neural retina over time from its initial formation to the mature structure. The neural retina is the part of the retina that contains neurons and photoreceptor cells. |
positive regulation of bone mineralization | Any process that activates or increases the frequency, rate or extent of bone mineralization. |
positive regulation of calcium ion transport | Any process that activates or increases the frequency, rate or extent of the directed movement of calcium ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore. |
regulation of blood pressure | Any process that modulates the force with which blood travels through the circulatory system. The process is controlled by a balance of processes that increase pressure and decrease pressure. |
regulation of cellular response to insulin stimulus | Any process that modulates the frequency, rate or extent of cellular response to insulin stimulus. |
regulation of cytosolic calcium ion concentration | Any process involved in the maintenance of an internal steady state of calcium ions within the cytosol of a cell or between the cytosol and its surroundings. |
regulation of vascular associated smooth muscle contraction | Any process that increases the frequency, rate or extent of vascular smooth muscle contraction. |
