It has been implicated in fundamental cellular processes as diverse as cell differentiation, signal transduction, and regulated exocytosis. However, no information is available about the existence of ahnak isoforms that serve different cell type-specific functions. In cardiomyocytes we identified ahnak as a 700 kDa protein that localized to the inner side of the sarcolemma membrane and interacted with the ß subunit
