[en] Calcium has been unequivocally regarded as a key signal messenger in almost every cell type. Calcium regulates a number of important cellular functions including cell growth, myofilament contraction, cell survival and apoptosis as well as gene transcription. A complex regulatory mechanism of cellular calcium is needed to fine tune the precise calcium concentration in each subcellular location and also to transmit the signals carried by the calcium pool to the correct end target. In this article we will review the recently emerging role of the plasma membrane calcium/calmodulin dependent ATPase isoform 4 (PMCA4) in regulating calcium signalling. We will then focus on the function of this molecule in cardiomyocytes, in which PMCA4 forms protein-protein interactions with several key signalling molecules. Recent evidence has shown in vivo physiological functionalities and possible clinical implications of the PMCA4 signalling complex. This article is part of a Special Issue entitled: 11th European Symposium on Calcium.
