A docking site per calcium channel cluster

A study co-led by Ryuichi Shigemoto and Alain Marty concludes that a single docking site may use a single cluster of calcium channels, and that both the number of docking sites and the number of calcium clusters change in ...

Unexpected role for calcium ion channel protein revealed

A new study published in Nature Communications and co-authored by Northwestern Medicine scientists shows how two proteins of the Ca2+ release-activated Ca2+ (CRAC) channel family interact with each other to control the flow ...

Scientists find sensor that makes synapses fast

Synapses, the connections between neurons, come in different flavors, depending on the chemical they use as transmitter. Signal transmitters, or neurotransmitters, are released at the synapse after calcium ions flow into ...

How neurons talk to each other

Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers. Reinhard Jahn, Director at the Max Planck Institute for Biophysical Chemistry in Göttingen, has ...

Guarding the gatekeepers

Information flow in cells relies on calcium as a key agent in several signalling pathways. Calcium dependent signalling is crucial in nearly every aspect of life - muscle movement, immune reactions, nerve function, light ...
