FunFam 80: neurexin 3 isoform X1

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 5 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 channel regulator activity GO:0005246
Modulates the activity of a calcium channel.
1 Q6P9K9 (/IGI)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 Q6P9K9 (/IPI)
Signaling receptor activity GO:0038023
Receiving a signal and transmitting it in the cell to initiate a change in cell activity. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response.
1 Q9Y4C0 (/TAS)
Cell adhesion molecule binding GO:0050839
Interacting selectively and non-covalently with a cell adhesion molecule.
1 Q9Y4C0 (/TAS)
Neuroligin family protein binding GO:0097109
Interacting selectively and non-covalently with a member of the neuroligin protein family, neuronal cell surface proteins that mediate synapse formation.
1 Q9Y4C0 (/TAS)

There are 10 GO terms relating to "biological process"

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
Neuron cell-cell adhesion GO:0007158
The attachment of a neuron to another cell via adhesion molecules.
1 Q9Y4C0 (/TAS)
Chemical synaptic transmission GO:0007268
The 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.
1 Q6P9K9 (/IGI)
Neurotransmitter secretion GO:0007269
The regulated release of neurotransmitter from the presynapse into the synaptic cleft via calcium-regulated exocytosis during synaptic transmission.
1 Q6P9K9 (/IGI)
Axon guidance GO:0007411
The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.
1 Q9Y4C0 (/TAS)
Synapse assembly GO:0007416
The aggregation, arrangement and bonding together of a set of components to form a synapse. This process ends when the synapse is mature (functional).
1 Q6P9K9 (/IGI)
Learning GO:0007612
Any process in an organism in which a relatively long-lasting adaptive behavioral change occurs as the result of experience.
1 Q9Y4C0 (/IGI)
Adult behavior GO:0030534
Behavior in a fully developed and mature organism.
1 Q9Y4C0 (/IGI)
Social behavior GO:0035176
Behavior directed towards society, or taking place between members of the same species. Occurs predominantly, or only, in individuals that are part of a group.
1 Q9Y4C0 (/IGI)
Vocalization behavior GO:0071625
The behavior in which an organism produces sounds by a mechanism involving its respiratory system.
1 Q9Y4C0 (/IGI)
Regulation of synaptic vesicle exocytosis GO:2000300
Any process that modulates the frequency, rate or extent of synaptic vesicle exocytosis.
1 Q6P9K9 (/IMP)

There are 5 GO terms relating to "cellular component"

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
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 Q9Y4C0 (/TAS)
Integral component of plasma membrane GO:0005887
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.
1 Q9Y4C0 (/TAS)
Protein-containing complex GO:0032991
A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together.
1 Q6P9K9 (/IPI)
Presynaptic membrane GO:0042734
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.
1 Q6P9K9 (/ISA)
GABA-ergic synapse GO:0098982
A synapse that uses GABA as a neurotransmitter. These synapses are typically inhibitory.
