calcium ion transport

The directed movement of calcium (Ca) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

GO:0017158

regulation of calcium ion-dependent exocytosis

Any process that modulates the frequency, rate or extent of calcium ion-dependent exocytosis.

NAS

GO:0051592

response to calcium ion

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.

ISS

BP

GO:0055074

calcium ion homeostasis

Any process involved in the maintenance of an internal steady state of calcium ions within an organism or cell.

GO:0070588

calcium ion transmembrane transport

A 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.

IDA|TAS

BP

GO:1990035

calcium ion import into cell

The directed movement of calcium ions from outside of a cell into the cytoplasmic compartment. This may occur via transport across the plasma membrane or via endocytosis.

CC

GO:0005886

plasma membrane

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

IDA|TAS

CC

GO:0005887

integral component of plasma membrane

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

CC

GO:0070062

extracellular exosome

A membrane-bounded vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.

IDA

MF

GO:0005262

calcium channel activity

Enables the facilitated diffusion of a calcium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.

IDA|TAS

MF

GO:0005515

protein binding

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

IPI

MF

GO:0005516

calmodulin binding

Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states.

IDA

MF

GO:0046872

metal ion binding

Interacting selectively and non-covalently with any metal ion.
