Ras inhibits Jun-activated human atrial natriuretic peptide gene transcription in cultured ventricular myocytes.

abstract：:We studied product inhibition of the actin-activated ATPase of myosin subfragment-1 (S-1) from the three types of muscle tissue: skeletal, cardiac, and smooth. Increasing levels of [MgADP] in the 0-1-mM range caused significant inhibition of the actin-activated MgATPase activity of cardiac and gizzard but not skeletal...
