We are interested in how gametes, sperm and oocytes, are produced in mammals. In particular, we investigate which of the germ cell-specific genes are essential for successful production of gametes and which particular molecular pathways they are involved in. We utilize gene knockout technologies and molecular biology approaches to define physiological roles of these genes and the molecular mechanisms by which they regulate germ cell development. Currently, our efforts are focused on the following three topics: (1) the regulation of protein turnover by ubiquitination during spermiogenesis; (2) the control of cytoplasm removal during sperm individualization and spermiation (sperm release); (3) physiological roles of germ cell-specific small non-coding RNAs. Our study is important not only for the identification of causative genes of human infertility, but also for the development of non-hormonal contraceptives.
