RLC phosphorylation amplifies Ca2+ sensitivity of force in myocardium from cMyBP-C knockout mice, say Kyrah Turner, Bertrand Tanner @BertTannerLab and colleagues @WSUPullman: https://t.co/DORwxmIs98

Cardiomyocyte sarcomere length variability: Membrane fluorescence versus second harmonic generation myosin imaging. A new study from Oleg Lookin, Pieter de Tombe, Olivier Cazorla @umontpellier and colleagues https://t.co/rbvKnZ2HIW
#CellMotility #MyofilamentFunction #Biophysics
Kyrah Turner, Bertrand Tanner et al. @BertTannerLab @WSUPullman indicate that cMyBP-C and RLC may act in concert to regulate contractility in healthy and diseased cardiac muscles. https://t.co/DORwxmIs98

Myosin-binding protein C stabilizes, but is not the sole determinant of SRX myosin in cardiac muscle, say Shane Nelson, David Warshaw and colleagues @uvmvermont: https://t.co/y4Ky1PRooK

Image shows effects of Ca 2+ and ATP on fluorescence intensity and lifetime in IANBD-cTnC T53C exchanged myofibrils. From Alexey Dvornikov, Brett Colson and colleagues @UAZHealth: https://t.co/vUIyAX44Ee
#Biophysics #MyofilamentFunction
In @JGenPhysiol, Lookin, de Tombe, Cazorla et al. @umontpellier show that cardiomyocyte sarcomere length (SL) variability assessed by second-harmonic generation (SHG) was significantly less than that by ANEPPS confocal fluorescence. https://t.co/Ln2ncsDeNb
#MyofilamentFunction
Nelson, Warshaw et al. @uvmvermont show that observing the turnover of single ATP molecules within cardiac sarcomeres defines the spatial arrangement of super-relaxed myosin & their regulation by myosin-binding protein C. https://t.co/y4Ky1PRooK
