Phototropins (phot) are blue light receptors in plants which are involved in phototropism, stomatal opening, and chloroplast movements. Phototropin has two LOV domains (LOV1 and LOV2), and the LOV2 domain is responsible for activation of Ser/Thr ... Read more...
30 Jul 2009 Cone photoreceptors of the vertebrate retina terminate their response to light much faster than rod photoreceptors. However, the molecular mechanisms underlying this rapid response termination in cones are poorly understood. The experiments ... Read more...
11 May 2009 The retina can function under a variety of adaptation conditions and stimulus paradigms. To adapt to these various conditions, modifications in the phototransduction cascade and at the synaptic and network levels occur. In this paper, we focus on ... Read more...
