The product of proliferation disrupter is concentrated at centromeres and required for mitotic chromosome condensation and cell proliferation in Drosophila.

Abstract excerpt

Homozygosity for a null mutation in the proliferation disrupter (prod) gene of Drosophila causes decreased mitotic index, defects of anaphase chromatid separation, and imperfect chromosome condensation in larval neuroblasts and other proliferating cell populations. The defective condensation is especially obvious near the centromeres. Mutant larvae show slow growth and massive cell death in proliferating cell...
