Abstract

AIM: The aim of the study was to assess the function of human skeletal muscle myosin across a wide range of temperatures, including physiological. METHODS: We used a single fibre in vitro motility assay. The in vitro motility speed of actin filaments propelled by myosin extracted from fibres expressing type I myosin heavy chain (MyHC; n = 9), IIa MyHC (n = 6), IIax MyHC (n = 4) and I/IIa MyHC (n = 1) was measured at 15, 20, 25, 30 and 35 degrees C. RESULTS: The motility speed between groups of fibres expressing different MyHC differed significantly (P
