FunFam 165: Calbindin 2

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 4 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Calcium ion binding GO:0005509
Interacting selectively and non-covalently with calcium ions (Ca2+).

Calcium ion binding GO:0005509
Interacting selectively and non-covalently with calcium ions (Ca2+).
1 Q08331 (/ISO)
Calcium ion binding involved in regulation of presynaptic cytosolic calcium ion concentration GO:0099534
The directed change of presynaptic cytosolic free calcium ion concentration in the cytosol via the reversible binding of calcium ions to calcium-binding proteins in the cytosol thereby modulating the spatial and temporal dynamics of changes in presynaptic cytosolic calcium concentrations.

GO Term Annotations Evidence
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
4 A0A140VK08 (/IDA) A0A140VK08 (/IDA) P22676 (/IDA) P22676 (/IDA)
Nucleus GO:0005634
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.
2 P47728 (/IDA) P47728 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
2 P47728 (/IDA) P47728 (/IDA)
Stereocilium GO:0032420
An actin-based protrusion from the apical surface of auditory and vestibular hair cells and of neuromast cells. These protrusions are supported by a bundle of cross-linked actin filaments (an actin cable), oriented such that the plus (barbed) ends are at the tip of the protrusion, capped by a tip complex which bridges to the plasma. Bundles of stereocilia act as mechanosensory organelles.
2 P47728 (/IDA) P47728 (/IDA)
Cuticular plate GO:0032437
A dense network of actin filaments found beneath the apical cell surface of hair cells, and into which stereocilia are inserted.
2 P47728 (/IDA) P47728 (/IDA)
Terminal bouton GO:0043195
Terminal inflated portion of the axon, containing the specialized apparatus necessary to release neurotransmitters. The axon terminus is considered to be the whole region of thickening and the terminal bouton is a specialized region of it.
2 P47728 (/HDA) P47728 (/HDA)
Synaptic membrane GO:0097060
A specialized area of membrane on either the presynaptic or the postsynaptic side of a synapse, the junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell.
2 P47728 (/EXP) P47728 (/EXP)
Synaptic membrane GO:0097060
A specialized area of membrane on either the presynaptic or the postsynaptic side of a synapse, the junction between a nerve fiber of one neuron and another neuron or muscle fiber or glial cell.
