The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Voltage-gated potassium channels. Chain C
".
FunFam 84: Cation channel sperm associated 2
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 1 GO terms relating to "molecular function"

|
Fertilization GO:0009566
The union of gametes of opposite sexes during the process of sexual reproduction to form a zygote. It involves the fusion of the gametic nuclei (karyogamy) and cytoplasm (plasmogamy).
|
1 | A2ARP9 (/IMP) |
|
Flagellated sperm motility GO:0030317
Any process involved in the controlled movement of a flagellated sperm cell.
|
1 | A2ARP9 (/IMP) |
|
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 | Q96P56 (/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 | Q96P56 (/TAS) |
|
Sperm capacitation GO:0048240
A process required for sperm to reach fertilization competence. Sperm undergo an incompletely understood series of morphological and molecular maturational processes, termed capacitation, involving, among other processes, protein tyrosine phosphorylation and increased intracellular calcium.

| GO Term | Annotations | Evidence |
|---|---|---|
|
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.
|
2 | Q6AXP6 (/ISS) Q96P56 (/ISS) |
|
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 | Q96P56 (/TAS) |
|
Sperm flagellum GO:0036126
A microtubule-based flagellum (or cilium) that is part of a sperm, a mature male germ cell that develops from a spermatid.
|
1 | A2ARP9 (/IDA) |
|
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.
