Outline of Final Research Achievements

The localization of spermatogenic protein, Argonaute 2 (Ago2) function to interfer the transcription was identified on the rat testis. Ago2 was localized germ cell specific organelle, “Nuage” during the development on spermatocyte to spermatid. Moreover, the co-localization of Ago2 and lysosome membrane protein, LAMP2 in the clear vesicles surrounded on the Chromatoid body was identified by the Immunoelectron microscopic analysis in the late stage of spermatid. These results suggest that not only Ago2 modulate transcription of RNA in nuage structure but also related on the lysosome pathway in the late CB.
