Myosin light chain phosphatase: it gets around.
The importance of Ca 2 /calmodulin-dependent myosin light chain kinase (MLCK) for smooth muscle contraction is well documented.1 Until recently, myosin light chain (MLC) phosphatase was thought to be unregulated and constitutively active. However, studies have demonstrated that smooth muscle contraction is dependent on regulation of MLC phosphatase activity.2,3 The inhibition of phosphatase act...
متن کاملPlant blue-light receptors.
Plants have several blue-light receptors, which regulate different aspects of growth and development. Recent studies have identified three such receptors: cryptochrome 1, cryptochrome 2 and phototropin. Cryptochromes 1 and 2 are photolyase-like receptors that regulate hypocotyl growth and flowering time; phototropin mediates phototropism in response to blue light. In addition, phytochrome A has...
متن کاملBlue light-induced chloroplast relocation.
Chloroplast relocation movement is induced by blue light in most plants tested. Under weak light, chloroplasts move toward a brighter area in a cell (called low-fluence-rate response or accumulation movement), but they avoid strong light and move away from the light (called high-fluence-rate response or avoidance movement). Recently, mutants deficient in the chloroplast avoidance movement were ...
متن کاملSimultaneous blue, green, and red emission from diblock copolymer micellar films: a new approach to white-light emission.
White-light emission is achieved from a single layer of diblock copolymer micelles containing green- and red-light-emitting dyes in the separate micellar cores and blue-light-emitting polymer around their periphery, in which fluorescence resonance energy transfer between fluorophores is inhibited due to micelle isolation, resulting in simultaneous emission of these three species.
متن کاملBlue light hazard and aniridia.
The fundi of three patients with aniridia were photographed with a 470 nm illuminating light source. No apparent change in contrast was observable throughout the macular region. This would suggest an absence of the macular pigment. The likelihood of aniridics being more susceptible than normal persons to blue light damage is discussed.
