Revisiting the SRX paradox for myosin and myofibrils

Kerry Y. Kao, Kalen Z. Robeson, Anthony Asencio…·Michael Regnier

The paper re-examines the SRX state in myosin using mant-ATP displacement assays and finds no evidence of the SRX state in isolated myosin but detects two components in myofibrils, suggesting distinct myosin populations in thick filaments.

The E525K β-Myosin Mutation Causes Hypocontractility in Cardiomyocytes Without Altering Crossbridge Cycling

Kalen Z. Robeson, Timothy S. McMillen, Kristina Bezold Kooiker…·Michael Regnier

This study shows that the E525K β-myosin mutation reduces cardiomyocyte contraction without altering crossbridge cycling, through structural and computational analysis.
