Ion channels and Ca(2+)-handling proteins involved in the regulation of cardiac
electrophysiology and contractility are organized in macromolecular multiprotein
complexes. Recent molecular and cellular studies have significantly enhanced our
understanding of the composition of these macromolecular complexes and have
helped to elucidate their role in the dynamic regulation of ion channel function.
Moreover, it has become clear that alterations in the composition of ion channel
macromolecular complexes, for example, due to genetic mutations or acquired
alterations in the expression of individual components, may lead to ion channel
dysfunction and arrhythmogenesis. Here, we review novel insights into the
composition of the major ion channel macromolecular complexes and discuss the
potential clinical significance of alterations in these dynamic multiprotein
structures.
