Ca2+ channels and transmitter release at the active zone

Ralf Schneggenburger, Olexiy Kochubey, Yunyun Han

Ca2+-dependent transmitter release is the most important signaling mechanism for fast information transfer between neurons. Transmitter release takes places at highly specialized active zones with sub-micrometer dimension, which contain the molecular machi ...

An Exclusion Zone for Ca2+ Channels around Docked Vesicles Explains Release Control by Multiple Channels at a CNS Synapse

Henry Markram, Ralf Schneggenburger, Olexiy Kochubey, Felix Schürmann, Yunyun Han, Daniel Keller, Zsolt Norbert Babai

The spatial arrangement of Ca2+ channels and vesicles remains unknown for most CNS synapses, despite of the crucial importance of this geometrical parameter for the Ca2+ control of transmitter release. At a large model synapse, the calyx of Held, transmitt ...

RIM1 and RIM2 redundantly determine Ca2+ channel density and readily releasable pool size at a large hindbrain synapse

Ralf Schneggenburger, Yunyun Han, Zsolt Norbert Babai

The localization and density of voltage-gated Ca2+ channels at active zones are essential for the amount and kinetics of transmitter release at synapses. RIM proteins are scaffolding proteins at the active zone that bind to several other presynaptic protei ...
