FunFam 33: potassium voltage-gated channel subfamily A member...

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
Intracellular cyclic nucleotide activated cation channel activity GO:0005221
Enables the transmembrane transfer of a cation by a channel that opens when intracellular cyclic nucleotide has been bound by the channel complex or one of its constituent parts.
1 Q16322 (/TAS)
Voltage-gated potassium channel activity GO:0005249
Enables the transmembrane transfer of a potassium 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 B2RQA1 (/ISO)
Voltage-gated potassium channel activity GO:0005249
Enables the transmembrane transfer of a potassium 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 Q9I829 (/ISS)
Delayed rectifier potassium channel activity GO:0005251
Enables the transmembrane transfer of a potassium ion by a delayed rectifying voltage-gated channel. A delayed rectifying current-voltage relation is one where channel activation kinetics are time-dependent, and inactivation is slow.
1 Q9I829 (/ISS)

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
Potassium ion transport GO:0006813
The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 B2RQA1 (/ISO)
Potassium ion transport GO:0006813
The directed movement of potassium ions (K+) into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 Q16322 (/TAS)
Magnesium ion homeostasis GO:0010960
Any process involved in the maintenance of an internal steady state of magnesium ions within an organism or cell.
1 Q9I829 (/ISS)
Regulation of membrane potential GO:0042391
Any process that modulates the establishment or extent of a membrane potential, the electric potential existing across any membrane arising from charges in the membrane itself and from the charges present in the media on either side of the membrane.
1 Q9I829 (/ISS)
Potassium ion transmembrane transport GO:0071805
A process in which a potassium ion is transported from one side of a membrane to the other.
1 Q9I829 (/ISS)

There are 4 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 B2RQA1 (/ISO)
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 Q16322 (/TAS)
Paranode region of axon GO:0033270
An axon part that is located adjacent to the nodes of Ranvier and surrounded by lateral loop portions of myelin sheath.
1 Q9I829 (/ISS)
Juxtaparanode region of axon GO:0044224
A region of an axon near a node of Ranvier that is between the paranode and internode regions.
