FunFam 23: Acetylcholine receptor subunit beta-like 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.

Any process that modulates the frequency, rate or extent of muscle contraction.
1 P48182 (/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 P04755 (/IEP)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.
1 P48181 (/IDA)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.

The process of synaptic transmission from a neuron to a muscle, across a synapse.
1 P48182 (/IMP)
Regulation of gene expression GO:0010468
Any process that modulates 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.

Neuron projection GO:0043005
A prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

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.

Neuronal cell body GO:0043025

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 P04755 (/ISS)
Synapse GO:0045202
The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.
