The mitotic spindle defects (monopolar spindle) observed in embryos fathered by Poc1W45R mutant males are rescued by paternal expression of Poc1ABGFP.
Combination with Poc1ABGFP also restores the giant centriole size defect as well as the sperm immotility characteristic for Poc1W87X mutant males. Paternal expression of Poc1ABGFP also significantly rescues the embryonic phenotypes of progeny from Poc1W87X fathers (developmental delay, mitotic defects).
