Supplementary information

Rabphilin 3A also known as RPH3A plays a role in exocytosis and synaptic transmission. This protein has a molecular weight of approximately 85 kDa. It contains domains that help in the interaction with small GTPases and phospholipids in the membrane. Rabphilin 3A is expressed in brain tissues particularly in neurons. It associates with synaptic vesicle membranes which is essential for neurotransmitter release at synapses.
Biological function summary

Rabphilin 3A modulates synaptic vesicle docking and fusion in the neuron. It acts as an effector of the small GTPase Rab3 forming a complex that links synaptic vesicles to presynaptic membranes. This interaction influences the dynamics of the membrane and ensures proper vesicle cycling during neurotransmission. Rabphilin 3A also interacts with calcium ions which regulate its affinity for other proteins involved in the synaptic machinery.

Pathways

Rabphilin 3A participates in the regulation of the neurotransmitter release pathway and synaptic vesicle cycle. It interacts with proteins like Rab3A to facilitate vesicle docking and membrane fusion important for synaptic vesicle exocytosis. The cAMP-dependent signaling pathway also involves Rabphilin 3A guiding the processes associated with synapse communication and plasticity.

Rabphilin 3A appears to play a role in neurological disorders like epilepsy and neurodegenerative diseases. Its dysfunction is connected to altered synaptic transmission a factor in epilepsy pathophysiology. Rab3A a protein closely associated with Rabphilin 3A also impacts synaptic activity and their interplay may contribute to understanding diseases affecting synaptic function. Changes in Rabphilin 3A expression or function can lead to imbalances in neurotransmitter release highlighting its potential link to neurodegenerative conditions like Alzheimer's disease.

Target data

Plays an essential role in docking and fusion steps of regulated exocytosis (PubMed : 16203731, PubMed : 8617225). At the presynaptic level, RPH3A is recruited by RAB3A to the synaptic vesicle membrane in a GTP-dependent manner where it modulates synaptic vesicle trafficking and calcium-triggered neurotransmitter release (PubMed : 8617225). In the post-synaptic compartment, forms a ternary complex with GRIN2A and DLG4 and regulates NMDA receptor stability (PubMed : 26679993). Also plays a role in the exocytosis of arginine vasopressin hormone (PubMed : 29367474).
