...) the ratio of two troponin T isoforms changed from head to tail and (ii) caudal muscle had a lower total parvalbumin content than rostral muscle. Since troponin T and parvalbumin have been implicated in the regulation of skeletal muscle kinetics, longitudinal variation in muscle contraction kinetics...

... change in protein expression, which alters the Ca 2+ -sensitivity of muscle activation and twitch contraction kinetics. The alternatively spliced Ca 2+ regulatory protein troponin T (TnT) undergoes an isoform shift during adult maturation. Skinned (demembranated) fibers of mature flight muscle are up...

The flagella are noteworthy for the high frequency at which they operate, 10–16 Hz in different species ( Burrows and Willows...
