The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:

"
Acid-sensing ion channel domain

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 1 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
Sodium channel activity GO:0005272
Enables the facilitated diffusion of a sodium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
1 Q9VL84 (/ISS)

There are 6 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
Sodium ion transport GO:0006814
The directed movement of sodium ions (Na+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 Q9VL84 (/ISS)
Response to salt stress GO:0009651
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 stimulus indicating an increase or decrease in the concentration of salt (particularly but not exclusively sodium and chloride ions) in the environment.
1 Q9VL84 (/IMP)
Liquid clearance, open tracheal system GO:0035002
The clearance of liquid from the epithelial tubes of an open tracheal system, shortly before the emergence of the larva, to generate an air-filled tubule system.
1 Q9VL84 (/IMP)
Salt aversion GO:0035199
The specific avoidance actions or reactions of an organism in response to the perception of salt.
1 Q9VL84 (/IMP)
Sensory perception of salty taste GO:0050914
The series of events required to receive a salty taste stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process.
1 Q9VL84 (/IMP)
Regulation of synaptic activity GO:0060025
Any process that modulates the frequency, rate or extent of synaptic activity, the controlled release of neurotransmitters into the synaptic cleft and their subsequent detection by a postsynaptic cell.
1 Q9VL84 (/IMP)

There are 1 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
Integral component of membrane GO:0016021
The component of a 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.
