Summary
Phase separation organizes presynaptic proteins into condensates, impacting synapse formation and function. This review explores the in vivo roles of this crucial cellular mechanism in neuronal communication.
Area of Science:
- Neuroscience
- Cell Biology
- Biochemistry
Background:
- Synapses are fundamental to nervous system function.
- Molecular mechanisms of synaptic assembly and function are well-studied.
- Phase separation is an emerging principle of synaptic protein organization.
Purpose of the Study:
- To review emerging evidence for the in vivo functional roles of phase separation at the presynapse.
- To discuss future research directions for understanding synaptic phase separation.
Main Methods:
- Review of existing literature on synaptic phase separation.
- Analysis of in vivo functional studies on presynaptic condensates.
Main Results:
- Presynaptic active zone components and synaptic vesicle-clustering factors form phase-separated condensates or hydrogels.
- In vivo studies demonstrate phase separation's impact on synapse formation and function.
Conclusions:
- Phase separation represents a critical layer of protein organization at the presynapse.
- Further in vivo studies are needed to elucidate the complexity of synaptic phase separation and its functional implications.

130.0K
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.

Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...
