Outline of Final Research Achievements

Deletion of intercellular bridge (ICB), which connects all germ cells, caused male infertility. But the function of ICB still remains unknown. To understand the significance of ICB in spermatogenesis, its associating factors were identified and the interactions among each identified protein were comprehensively profiled. Specific antibodies to selected target proteins were developed and used to analyze their localization in testis. As a result, a novel Ectoplasmic Specialization (EPS) associating protein, KIAA1210, was identified. The knockout mouse of KIAA1210 was successfully produced and is under analyses. The results from analyses of KIAA1210 deficient mice will bring deep understandings of interactions between ICB and the other cell junction in spermatogenesis.
