Overview of Gene Research
Rims1, also known as Rab3-interacting molecule 1, is a key protein involved in neurotransmitter release. It is associated with the neurotransmitter release cycle and the organization of presynaptic active zones. Rims1 forms dynamic and condensed assemblies with RIM-BP through liquid-liquid phase separation, which can enrich voltage-gated Ca2+ channels for efficient synaptic transmissions [1]. It is also involved in the cAMP-EPAC-PKCε-RIM1α signaling cascade that regulates presynaptic long-term potentiation and motor learning [3].
In a study generating dopamine-neuron-specific knockout mice of RIM (a form of gene knockout), action-potential-induced dopamine release was disrupted. These mice showed strongly impaired rapid in vivo dopamine dynamics, yet baseline dopamine persisted and supported spontaneous movement. However, reward-oriented behavior was impaired in these knockout mice, suggesting that Rims1-mediated action-potential-induced dopamine release is dispensable for movement initiation but promotes motivation and performance during reward-guided behaviors [2].
In conclusion, Rims1 is crucial for neurotransmitter release and the regulation of synaptic function. The gene knockout mouse models have revealed its role in differentiating between motor function and reward-oriented behaviors, contributing to our understanding of how the nervous system controls movement and motivation.
