Heterotrimeric G proteins in vertebrates constitute a family molecular switches that transduce
the activation of a populous group of cell-surface receptors to a group of diverse effector …

Vertebrate and invertebrate visual photoreceptors detect light with exquisite sensitivity and
rapid kinetics. They can detect single photons and by adapting to background light respond …

Low power laser irradiation has been reported to cause biological effects due to the
photochemical and/or photophysical action of the radiation. This study determined …

Publisher Summary This chapter describes the structural aspects of different photoreceptive
organelles including their interaction with cytoskeletal elements. It also examines the …

Broadcast spawning corals release gametes into the oceans with extraordinarily accurate
timing. While the date of spawning is set by the lunar cycle, the hour/minute of spawning is …

The present models of phototransduction for vertebrates and invertebrates have been
reviewed and the relative literature updated. The emerging picture for vertebrate …

Retinal organoids (ROs) derived from human inducible pluripotent stem cells (hiPSCs)
exhibit considerable therapeutic potential. However, current quality control of ROs during in …

For many animals, evolution has selected for complex visual systems despite the high
energetic demands associated with maintaining eyes and their processing structures …

Interaction of G-protein with photoactivated rhodopsin (Rh∗) in crayfish photoreceptor
membranes was investigated by immunoprecipitation using an antibody against rhodopsin …

Publisher Summary This chapter discusses the structure and function of invertebrate visual
pigments (VP). VPs constitute the interface between the photophysical processes of light …
