shrub is required for spermatogenesis of Drosophila melanogaster.

Shrub (CG8055) encodes the vps32/snf7 protein, a filament-forming subunit of the ESCRT (endosomal sorting complexes required for transport)-III complex involved in inward membrane budding. It was reported that shrub was required for abscission in female germline stem cells. In this study, we showed that the expression level of shrub in the testis was significantly higher than that in the ovary of 1-day-old Drosophila melanogaster, suggesting a role in male reproduction.
