The biochemistry of neurotransmitter secretion.

The progress that has resulted from the convergence of biochemistry with yeast genetics has accelerated the pace at which the molecular events of membrane transport are being elucidated. Future research will focus not only on testing the proposed sequence of protein-protein interactions but also on identifying how calcium regulation is imposed on this system. As our understanding of the basic mechanisms of neurosecretion increases, attention will undoubtedly shift to how the molecules of release are modified to produce changes in synaptic efficacy.
