Calcium Signaling

The processes that use or regulate calcium as a biological signal to transmit information or initiate functions such as exocytosis, synaptic signaling, and contraction are highly developed and specialized for the functional needs of a particular tissue. A large number of cellular proteins have evolved to either recognize, or to transmit biological calcium signals. The signaling between such proteins often occur in confined spaces over distances of a few nano-meters, leaving their detection ...
