Abstract:
Complex behaviors using wings have facilitated the insect evolutionary success and diversification. The Drosophila indirect flight muscles (IFM) have evolved a highly ordered myofilament lattice structure and uses oscillatory contractions by pronounced stretch activation mechanism to drive the wings for high powered flight subject to natural selection. Moreover, the IFM is also utilized during small amplitude wing vibrations for species-specific male courtship song (sine and pulse), an important Drosophila mating behavior subject to sexual selection. Unlike flight, the contractile mechanism an

The longitudinal muscle layer in gut is the functional opponent to the circular muscle layer during the peristalsis reflex. Differences in innervation of the layers allow for the contraction of one layer that corresponds with the simultaneous relaxation of the other, enabling the passage of gut contents in a controlled fashion. Differences in development have given the cells of the two layers differences in receptor populations, membrane lipid handling, and calcium handling profiles/behaviors. The kinase signaling differences between the two layers is not as well characterized. Upon activa

Abstract:
The regulatory light chain (RLC) of myosin is a component of the lever arm of the myosin motor in muscle thick filaments. Phosphorylation of RLC by myosin light chain kinase (MLCK) modulates the force and speed of muscle contraction, but the mechanisms of RLC‐mediated regulation in striated muscles are less well understood than those of Ca2+‐dependent regulation via troponin in the thin filament. To help elucidate the role of RLC in muscle regulation, its orientation in the native environment of cardiac muscle cells was measured. Pairs of cysteine residues were genetically introduced into the

Force generation and the ability of the heart muscle to contract and correspondingly to beat depends upon multiple interactions between myosin and actin-tropomyosin-troponin, the key proteins of the contractile apparatus. The myosin molecule consists of two heavy chains and two types of light chains, two essential (ELC) and two regulatory (RLC) light chains. We hypothesize that mutations in myosin ELC may affect the ability of myosin to bind to actin, thus producing structurally and/or functionally abnormal sarcomeres effecting heart muscle contraction and relaxation.

Background and aims: It is known that smooth muscle possesses substantial mechanical plasticity in that it is able to adapt to large changes in length without compromising its ability to generate force. It is believed that structural malleability of the contractile apparatus underlies this plasticity. There is strong evidence suggesting that myosin thick filaments of the muscle are relatively labile and their length in vivo is determined by the equilibrium between monomeric and filamentous myosin. The equilibrium in turn is governed by the state of phosphorylation of the 20-kD regulatory myosi

It is generally believed that the myosin thick filaments in smooth muscle are structurally less stable than those in striated muscle. In vitro studies have shown that phosphorylation of the 20-kD myosin light chain (MLC) facilitates formation of the thick filaments from monomeric myosins in solution. It appears that the structural integrity of the thick filaments can be enhanced by phosphorylation of the MLC. It is however not known whether the transition from monomeric to filamentous myosin occurs in intact smooth muscle when the light chains are phosphorylated during muscle activation.
