Outline of Final Research Achievements

We have tried to identify novel factors interacting with GCS1, the male-side gamete fusion factor conserved among animals, plants and protists, using the rodent malaria parasite Plasmodium berghei. We succeeded in producing parasites expressing GCS1 conjugated with BioID2, which was recently developed as a proximity-dependent biotin ligase. Although we have not been able to detect female-side partners of GCS1, our findings suggest a promising possibility to identify fertilization factors.

Academic Significance and Societal Importance of the Research Achievements

マラリアは蚊によって媒介される感染症であり、蚊の体内ではマラリア原虫が有性生殖によって増殖する。このことから、マラリア原虫の受精を妨げることがマラリア撲滅の戦略の一つとして現在注目されており、受精分子機構の解明が待たれている。本研究成果であるビオチン化酵素によるスクリーニング法は、マラリア原虫の受精に働く因子の効率的探索に大いに貢献するものであり、さらなる改善を加えることでマラリア原虫の受精機構解明に資する成果が期待できる。
