FunFam 57: 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 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
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 B1AYL1 (/IDA) Q62467 (/IDA)
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 F1LQQ7 (/TAS) P97706 (/TAS)
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.
1 Q01118 (/TAS)
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 B1AYL1 (/IPI)

There are 5 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.
3 F1LQQ7 (/TAS) P97706 (/TAS) Q01118 (/TAS)
Response to bacterium GO:0009617
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 from a bacterium.
2 B1AYL1 (/IEP) Q62467 (/IEP)
Sodium ion homeostasis GO:0055078
Any process involved in the maintenance of an internal steady state of sodium ions within an organism or cell.
2 B1AYL1 (/IDA) Q62467 (/IDA)
Sodium ion homeostasis GO:0055078
Any process involved in the maintenance of an internal steady state of sodium ions within an organism or cell.
2 B1AYL1 (/IMP) Q62467 (/IMP)
Muscle contraction GO:0006936
A process in which force is generated within muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis.
1 Q01118 (/TAS)

There are 2 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.
2 B1AYL1 (/IDA) Q62467 (/IDA)
Glial cell projection GO:0097386
A prolongation or process extending from a glial cell.
