J. Neurochem. (2011) 118 , 695–713. Abstract In recent years, substantial progress has been made towards an understanding of the physiological function of EF‐hand calcium sensor proteins of the Calmodulin (CaM) superfamily in neurons. This deeper appreciation is based on the identification of novel target interactions, structural studies and the discovery of novel signalling mechanisms in protein trafficking and synaptic plasticity, in which CaM‐like sensor proteins appear to play a role. However, not all interactions are of plausible physiological relevance and in many cases it is not yet clear how the CaM signaling network relates to the proposed function of other EF‐hand sensors. In this review, we will summarize these findings and address some of the open questions on the functional role of EF‐hand calcium binding proteins in neurons.
