WDR64, a testis-specific protein, is involved in the manchette and flagellum formation by interacting with ODF1.

ABSTRACT: The WD40 repeat (WDR) domain is present in a wide range of proteins, providing sites for protein‒protein interactions. Recent studies have shown that WDR proteins play indispensable roles in spermatogenesis, such as in spermatocyte division, sperm head formation and flagellar assembly. In this study, we identified a novel testis-specific gene, WDR64, which has the typical characteristics of WD40 proteins with two β-propellers, and is highly conserved in Mammalia. RT-PCR and Western blot results revealed that WDR64 was highly expressed in testis. WDR64 protein was weakly expressed at postnatal Day 7, increased substantially at postnatal Day 28 and maintained at high levels thereafter. Further immunofluorescence demonstrated that WDR64 was localized posterior to the nucleus in
