The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:
"Voltage-gated potassium channels. Chain C
".
FunFam 78: Cation channel sperm associated 1
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 2 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

|
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).

2 | Q8NEC5 (/IPI) Q91ZR5 (/IPI) |
|
Voltage-gated calcium channel activity GO:0005245
Enables the transmembrane transfer of a calcium 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.

|
Response to progesterone GO:0032570
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 progesterone stimulus.
|
1 | Q8NEC5 (/TAS) |
|
Sperm-egg recognition GO:0035036
The initial contact step made between the sperm plasma membrane and outer layer of the egg during fertilization.
|
1 | Q8NEC5 (/TAS) |
|
Regulation of calcium ion transport GO:0051924
Any process that modulates the frequency, rate or extent of the directed movement of calcium ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
|
1 | Q91ZR5 (/IMP) |
|
Regulation of cilium beat frequency involved in ciliary motility GO:0060296

CatSper complex GO:0036128
A sperm-specific voltage-gated calcium channel that controls the intracellular calcium ion concentration and, thereby, the swimming behavior of sperm. Consists of a heteromeric tetramer surrounding a calcium ion- selective pore. May also contain additional auxiliary subunits.
