FunFam 140: Neuronal acetylcholine receptor subunit eat-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 2 GO terms relating to "molecular function"

GO TermAnnotationsEvidence
Action potential GO:0001508
A process in which membrane potential cycles through a depolarizing spike, triggered in response to depolarization above some threshold, followed by repolarization. This cycle is driven by the flow of ions through various voltage gated channels with different thresholds and ion specificities.
1 Q9U298 (/IMP)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.
1 Q9U298 (/IMP)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.
1 Q60S81 (/ISS)
Determination of adult lifespan GO:0008340
The control of viability and duration in the adult phase of the life-cycle.
1 Q9U298 (/IGI)
Determination of adult lifespan GO:0008340
The control of viability and duration in the adult phase of the life-cycle.
1 Q9U298 (/IMP)
Determination of adult lifespan GO:0008340
The control of viability and duration in the adult phase of the life-cycle.
1 Q60S81 (/ISS)
Positive regulation of gene expression GO:0010628
Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
1 Q9U298 (/IMP)
Negative regulation of gene expression GO:0010629
Any process that decreases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
1 Q9U298 (/IMP)
Larval feeding behavior GO:0030536
Feeding behavior in a larval (immature) organism.
1 Q9U298 (/IMP)
Regulation of multicellular organism growth GO:0040014
Any process that modulates the frequency, rate or extent of growth of the body of an organism so that it reaches its usual body size.

GO TermAnnotationsEvidence
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.
1 Q9U298 (/IDA)
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.
1 Q60S81 (/ISS)
Acetylcholine-gated channel complex GO:0005892
A homo- or hetero-pentameric protein complex that forms a transmembrane channel through which ions may pass in response to acetylcholine binding.
1 Q9U298 (/IMP)
Acetylcholine-gated channel complex GO:0005892
A homo- or hetero-pentameric protein complex that forms a transmembrane channel through which ions may pass in response to acetylcholine binding.
1 Q60S81 (/ISS)
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.
