FunFam 23: Sodium channel protein

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 3 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
Voltage-gated sodium channel activity GO:0005248
Enables the transmembrane transfer of a sodium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
2 P35500 (/IDA) P35500 (/IDA)
Voltage-gated sodium channel activity GO:0005248
Enables the transmembrane transfer of a sodium ion by a voltage-gated channel. A voltage-gated channel is a channel whose open state is dependent on the voltage across the membrane in which it is embedded.
2 P35500 (/IMP) P35500 (/IMP)
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.
2 P35500 (/IMP) P35500 (/IMP)

There are 8 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
Response to hypoxia GO:0001666
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 lowered oxygen tension. Hypoxia, defined as a decline in O2 levels below normoxic levels of 20.8 - 20.95%, results in metabolic adaptation at both the cellular and organismal level.
2 P35500 (/IDA) P35500 (/IDA)
Mechanosensory behavior GO:0007638
Behavior that is dependent upon the sensation of a mechanical stimulus.
2 P35500 (/IMP) P35500 (/IMP)
Response to mechanical stimulus GO:0009612
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 mechanical stimulus.
2 P35500 (/IGI) P35500 (/IGI)
Response to mechanical stimulus GO:0009612
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 mechanical stimulus.
2 P35500 (/IMP) P35500 (/IMP)
Sodium ion transmembrane transport GO:0035725
A process in which a sodium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
2 P35500 (/IDA) P35500 (/IDA)
Sodium ion transmembrane transport GO:0035725
A process in which a sodium ion is transported from one side of a membrane to the other by means of some agent such as a transporter or pore.
2 P35500 (/IMP) P35500 (/IMP)
Male courtship behavior, veined wing generated song production GO:0045433
The process during wing vibration where the male insect produces a species-specific acoustic signal called a love song.
2 P35500 (/IMP) P35500 (/IMP)
Regulation of postsynaptic membrane potential GO:0060078
Any process that modulates the potential difference across a post-synaptic membrane.
2 P35500 (/IMP) P35500 (/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 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.
