Research Abstract

This research project aimed to elucidate signaling and molecular mechanisms of myofibrillar actin filament formation. We found that N-WASP bound to the SH3 domain of nebulette (Nebt) in the Z bands of cardiac myofibrils. The Nebt-N-WASP complex nucleated actin to form actin filaments from the Z-bands. Furthermore, Lmod2 bound to N-terminal region of Nebt and seemed to extend short actin filaments preformed by the Nebt-N-WASP complex. GSK-3beta phosphorylated Nebt C-terminal region, N-WASP, and Lmod2, possibly resulting in their inactivation or degradation. Transverse aortic constriction caused pathological cardiac hypertrophy, fibrosis, and deterioration of cardiac function in mice. Administration of IGF-1 to mice ameliorated these symptoms, whereas that of an N-WASP inhibitor worsened them. Thus, actin filament formation induced by N-WASP activated by IGF-1 signaling is required for normal cardiac functions by interfering with pathological cardiac phenotypes.
