FunFam 112: Acetylcholine receptor subunit alpha-type unc-63

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 list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Acetylcholine-gated cation-selective channel activity GO:0022848
Selectively enables the transmembrane transfer of a cation by a channel that opens upon binding acetylcholine.
1 Q9N587 (/IDA)
Acetylcholine-gated cation-selective channel activity GO:0022848
Selectively enables the transmembrane transfer of a cation by a channel that opens upon binding acetylcholine.

There are 8 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
Regulation of muscle contraction GO:0006937
Any process that modulates the frequency, rate or extent of muscle contraction.
1 Q9N587 (/IGI)
Synaptic transmission, cholinergic GO:0007271
The vesicular release of acetylcholine from a presynapse, across a chemical synapse, the subsequent activation of dopamine receptors at the postsynapse of a target cell (neuron, muscle, or secretory cell) and the effects of this activation on the postsynaptic membrane potential and ionic composition of the postsynaptic cytosol. This process encompasses both spontaneous and evoked release of neurotransmitter and all parts of synaptic vesicle exocytosis. Evoked transmission starts with the arrival of an action potential at the presynapse.
1 Q9N587 (/IMP)
Post-embryonic development GO:0009791
The process whose specific outcome is the progression of the organism over time, from the completion of embryonic development to the mature structure. See embryonic development.
1 Q9N587 (/IMP)
Ion transmembrane transport GO:0034220
A process in which an ion is transported across a membrane.
1 Q9N587 (/IMP)
Locomotion GO:0040011
Self-propelled movement of a cell or organism from one location to another.
1 Q9N587 (/IMP)
Regulation of locomotion GO:0040012
Any process that modulates the frequency, rate or extent of locomotion of a cell or organism.
1 Q9N587 (/IMP)
Regulation of oviposition GO:0046662
Any process that modulates the frequency, rate or extent of the deposition of eggs, either fertilized or not, upon a surface or into a medium.
1 Q9N587 (/IMP)
Calcium ion import across plasma membrane GO:0098703
The directed movement of calcium ions from outside of a cell, across the plasma membrane and into the cytosol.
1 Q9N587 (/IDA)

There are 3 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 Q9N587 (/IDA)
Neuromuscular junction GO:0031594
The junction between the axon of a motor neuron and a muscle fiber. In response to the arrival of action potentials, the presynaptic button releases molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane of the muscle fiber, leading to a change in post-synaptic potential.
1 Q9N587 (/IDA)
Postsynaptic membrane GO:0045211
A specialized area of membrane facing the presynaptic membrane on the tip of the nerve ending and separated from it by a minute cleft (the synaptic cleft). Neurotransmitters cross the synaptic cleft and transmit the signal to the postsynaptic membrane.
