FunFam 77: Potassium channel subfamily K member 5

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
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.
3 Q3T9D4 (/IDA) Q80XE0 (/IDA) Q9JK62 (/IDA)
Potassium channel activity GO:0005267
Enables the facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
3 A0A2R8PYU3 (/IDA) F1QSX2 (/IDA) Q32PR9 (/IDA)
Potassium channel activity GO:0005267
Enables the facilitated diffusion of a potassium ion (by an energy-independent process) involving passage through a transmembrane aqueous pore or channel without evidence for a carrier-mediated mechanism.
2 O95279 (/TAS) O95279 (/TAS)
Outward rectifier potassium channel activity GO:0015271
Enables the transmembrane transfer of a potassium ion by an outwardly-rectifying voltage-gated channel. An outwardly rectifying current-voltage relation is one where at any given driving force the outward flow of K+ ions exceeds the inward flow for the opposite driving force.
2 Q5RGB0 (/IDA) Q6PFU3 (/IDA)

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
Potassium ion import across plasma membrane GO:1990573
The directed movement of potassium ions from outside of a cell, across the plasma membrane and into the cytosol.
3 Q3T9D4 (/IDA) Q80XE0 (/IDA) Q9JK62 (/IDA)
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.
2 O95279 (/TAS) O95279 (/TAS)
Excretion GO:0007588
The elimination by an organism of the waste products that arise as a result of metabolic activity. These products include water, carbon dioxide (CO2), and nitrogenous compounds.
2 O95279 (/TAS) O95279 (/TAS)
Fin development GO:0033333
The process whose specific outcome is the progression of a fin over time, from its formation to the mature structure.
2 Q5RGB0 (/IMP) Q6PFU3 (/IMP)
Fin morphogenesis GO:0033334
The process in which the anatomical structures of a fin are generated and organized.
2 Q5RGB0 (/IMP) Q6PFU3 (/IMP)
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.
2 Q5RGB0 (/IDA) Q6PFU3 (/IDA)

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.
