RIMS binding protein 2 is a protein that in humans is encoded by the RIMBP2 gene. ^[5] This protein plays a significant role in synaptic transmission and is involved in the regulation of voltage-gated calcium channels, which are crucial for neurotransmitter release at synapses.^[6]^[7]

Function and characteristics

RIMBP2 is primarily located in the presynaptic active zones of neurons, where it contributes to the organization and maintenance of synaptic structures. It is essential for the proper functioning of synaptic vesicles and calcium-dependent processes that facilitate communication between neurons.^[8]^[9]

Clinical relevance

Research has indicated that mutations or dysregulation of RIMBP2 may be associated with various neurological disorders, such as Pitt-Hopkins syndrome.^[6]^[10]
