Leucine-rich repeats (LRRs) are protein motifs crucial for neuronal synapse function. This review highlights key synaptic LRR proteins involved in synapse formation, plasticity, and maintenance.
Area of Science:
- Neuroscience
- Molecular Biology
- Protein Science
Background:
- Leucine-rich repeats (LRRs) are conserved protein motifs mediating protein-protein interactions.
- LRR proteins are found in various cellular compartments, including the cell membrane and cytoplasm.
- Many LRR proteins exhibit significant roles in neuronal functions.
Purpose of the Study:
- To summarize an emerging group of synaptic LRR proteins.
- To discuss the involvement of these proteins in neuronal synapse biology.
Main Methods:
- Literature review of studies on synaptic LRR proteins.
- Analysis of the roles of identified LRR proteins in neuronal synapses.
Main Results:
- Identified key synaptic LRR proteins: densin-180, Erbin, NGL, SALM, and LGI1.
- These proteins are implicated in critical synaptic processes.
Conclusions:
- Synaptic LRR proteins represent a significant class of molecules regulating neuronal synapse development and function.
- Further research into these LRR proteins can elucidate mechanisms of synaptic formation, differentiation, maintenance, and plasticity.

Chemical Synapses
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...
