The major sperm cytoskeletal protein (MSP) functions in the crucial role of locomotion. Miller et al. found that, in the nematode, MSP also executes another critical step in reproduction: inducing the female's oocyte to come out of the arrest phase and to mature. These results suggest that other proteins with MSP-like domains, which are found in plants, fungi, and other animals, may also have a signaling role. Villeneuve provides a Perspective on the work done by Miller et al.
