FunFam 3: acid-sensing ion channel 3 isoform X6

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.

Cation channel activity GO:0005261
Enables the energy-independent passage of cations across a lipid bilayer down a concentration gradient.
1 Q708S6 (/IPI)
Ligand-gated sodium channel activity GO:0015280
Enables the transmembrane transfer of a sodium ion by a channel that opens when a specific ligand has been bound by the channel complex or one of its constituent parts.
1 Q708S6 (/IDA)
Acid-sensing ion channel activity GO:0044736
Enables the transmembrane transfer of a sodium ion by a neuronal, voltage-insensitive channel that opens when an extracellular proton has been bound by the channel complex.
