Discovery illuminates elusive proton channel gene in dinoflagellates
Date:10/24/2011

known Hv1 sequences, finding high sequence diversity among the single-celled species and among invertebrates. She interpreted this finding to suggest the possibility of other novel functions of Hv1 in these species.

"As in multicellular organisms, ion channels in dinoflagellates play various roles in regulating basic life functions, which make them targets for controlling dinoflagellate populations and behavior," the authors suggested.

Future research will show whether targeting proton channels might give us a handle on controlling dinoflagellate blooms that cause deadly red tides and are responsible for massive fresh kills. Certain dinoflagellate species produce some of the most deadly poisons known, such as saxitoxin, a neurotoxin 100,000 times more potent than cocaine. Paralytic shellfish poisoning occurs in humans who eat shellfish that have consumed toxic dinoflagellates.
