05 Nov New light sensing molecule found in the fruit fly brain
Six biological pigments known as rhodopsins play well-established functions in light-sensing from the fruit fly . Three of these also have light-independent functions in temperature sense. New study proves that a rhodopsin, Rh7, is expressed in the brain of fruit flies in which it modulates the fly’s day-night action cycles. The analysis appears in Nature and has been financed by the National Eye Institute, a part of the National Institutes of Health.
