Disrupting key protein alters biological rhythms in water flea
The E75 protein is a key regulator of some biological rhythms through interactions with nitric oxide. Suppression of E75 results in longer molt cycles and reduced numbers of offspring in the water flea, Daphnia magna. The work also raises questions about the ability of nitric oxide from environmental sources to disrupt biological rhythms that are critical to population sustainability.
