β2-subunit alternative splicing stabilizes Cav2.3 Ca channel activity during continuous midbrain dopamine neuron-like activity.

In dopaminergic (DA) (SN) neurons Cav2.3 R-type Ca-currents contribute to somatodendritic Ca-oscillations. This activity may contribute to the selective degeneration of these neurons in Parkinson's disease (PD) since Cav2.

RBP2 stabilizes slow Cav1.3 Ca channel inactivation properties of cochlear inner hair cells.

Cav1.3 L-type Ca channels (LTCCs) in cochlear inner hair cells (IHCs) are essential for hearing as they convert sound-induced graded receptor potentials into tonic postsynaptic glutamate release. To enable fast and indefatigable presynaptic Ca signaling, IHC Cav1.
