Implication

May inform cardiac myosin coordination models; leaves open targeted modulation in cardiomyopathies.

Key Points

To investigate the strain-sensitive mechanism of ADP release in myosin motors and its implications on muscle function.
Review of existing literature on ADP release mechanisms in fast and slow muscle myosins.
Analysis of the correlation between ADP release rate and muscle fiber shortening velocity.
Examination of strain-sensing mechanisms across different myosin types.
ADP release rate is linked to maximum shortening velocity in fast contracting muscle fibers.
Evidence supports a strain-sensitive mechanism in faster myosins that parallels findings from slower myosins.
A universal strain-sensing mechanism is proposed for all myosins, enabling coordinated motor action over distances.

Structured PICO

Population

Myosin motors (fast muscle myosins, slower muscle myosins, and non-muscle myosins such as myosin V)

The review argues that a strain-sensitive mechanism of ADP release is universal across all myosins, providing a way to coordinate multiple motor domains without classic allosteric communication.
